Added

• Add conversion webhook (#733).
• Add custom hbase.rest.endpoint property to the restserver hbase-site.xml (#708, #716).
  • The custom hbase.rest.hostname and native hbase.rest.port properties cannot be used for discovery advertisement, as these should remain stable regardless of listener class used to expose the REST service.

• Added support for HBase 2.6.3 (#695).
• Add end-of-support checker (#697).
  • EOS_CHECK_MODE (--eos-check-mode) to set the EoS check mode. Currently, only "offline" is supported.

• Changed env-vars to be consistent with config-utils in the entrypoint script (#700).
• BREAKING: The prometheus.io/scrape label moved from the headless Service to the metrics Service, which uses metrics as the port name instead of the previous ui-http/ui-https port name (#701).

[25.7.0] - 2025-07-23

[25.7.0-rc1] - 2025-07-18

Added

• BREAKING: Add listener support for HBase (#639).
• Adds new telemetry CLI arguments and environment variables (#652).
  • Use --file-log-max-files (or FILE_LOG_MAX_FILES) to limit the number of log files kept.
  • Use --file-log-rotation-period (or FILE_LOG_ROTATION_PERIOD) to configure the frequency of rotation.
  • Use --console-log-format (or CONSOLE_LOG_FORMAT) to set the format to plain (default) or json.
• Added support for HBase 2.6.2 (#659).
• Add RBAC rule to helm template for automatic cluster domain detection (#675).

Changed

• BREAKING: Replace stackable-operator initialize_logging with stackable-telemetry Tracing (#640, #648, #652).
  • The console log level was set by HBASE_OPERATOR_LOG, and is now set by CONSOLE_LOG_LEVEL.
  • The file log level was set by HBASE_OPERATOR_LOG, and is now set by FILE_LOG_LEVEL.
  • The file log directory was set by HBASE_OPERATOR_LOG_DIRECTORY, and is now set by FILE_LOG_DIRECTORY (or via --file-log-directory <DIRECTORY>).
  • Replace stackable-operator print_startup_string with tracing::info! with fields.
• BREAKING: Inject the vector aggregator address into the vector config using the env var VECTOR_AGGREGATOR_ADDRESS instead of having the operator write it to the vector config (#645).
• test: Bump to Vector 0.46.1 (#657).
• test: Bump OPA to 1.4.2 (#661).
• BREAKING: Previously this operator would hardcode the UID and GID of the Pods being created to 1000/0, this has changed now (#660)
  • The runAsUser and runAsGroup fields will not be set anymore by the operator
  • The defaults from the docker images itself will now apply, which will be different from 1000/0 going forward
  • This is marked as breaking because tools and policies might exist, which require these fields to be set
• BREAKING: Bump stackable-operator to 0.94.0 and update other dependencies (#675).
  • The default Kubernetes cluster domain name is now fetched from the kubelet API unless explicitly configured.
  • This requires operators to have the RBAC permission to get nodes/proxy in the apiGroup "". The helm-chart takes care of this.
  • The CLI argument --kubernetes-node-name or env variable KUBERNETES_NODE_NAME needs to be set. The helm-chart takes care of this.
• The operator helm-chart now grants RBAC patch permissions on events.k8s.io/events, so events can be aggregated (e.g. "error happened 10 times over the last 5 minutes") (#678).

Fixed

• Use json file extension for log files (#647).
• Fix a bug where changes to ConfigMaps that are referenced in the HbaseCluster spec didn't trigger a reconciliation (#645).
• Allow uppercase characters in domain names (#675).

Removed

• test: ZooKeeper 3.9.2 removed (#654).
• test: Remove HDFS 3.3.4, 3.3.6, and 3.4.0 (#655).
• test: HBase 2.4.18 removed (#659):
• Remove operator support for HBase 2.4 including the JMX exporter (#672).
• Remove the lastUpdateTime field from the stacklet status (#675).
• Remove role binding to legacy service accounts (#675).

[25.3.0] - 2025-03-21

Added

• The lifetime of auto generated TLS certificates is now configurable with the role and roleGroup config property requestedSecretLifetime. This helps reducing frequent Pod restarts (#598).
• Run a containerdebug process in the background of each HBase container to collect debugging information (#605).
• Aggregate emitted Kubernetes events on the CustomResources (#612).
• Support configuring JVM arguments (#620).
• Added support for HBase 2.6.1 (#627):

Removed

• BREAKING: The field config.hbaseOpts has been removed. Use JVM argument overrides instead to configure additional JVM arguments (#620).

Changed

• Bump stackable-operator to 0.87.0 and stackable-versioned to 0.6.0 (#634).
• Support moving regions to other Pods during graceful shutdown of region servers (#570).
• Default to OCI for image metadata and product image selection (#611).

[24.11.1] - 2025-01-09

Fixed

• BREAKING: Use distinct ServiceAccounts for the Stacklets, so that multiple Stacklets can be deployed in one namespace. Existing Stacklets will use the newly created ServiceAccounts after restart (#594).

[24.11.0] - 2024-11-18

Added

• The operator can now run on Kubernetes clusters using a non-default cluster domain. Use the env var KUBERNETES_CLUSTER_DOMAIN or the operator Helm chart property kubernetesClusterDomain to set a non-default cluster domain (#574).

Changed

• Reduce CRD size from 1.4MB to 96KB by accepting arbitrary YAML input instead of the underlying schema for the following fields (#548):
  • podOverrides
  • affinity
• Fix bug where the configuration of the hbaseRootdir at the role level is ignored (#584).

Fixed

• Implement envOverrides for HbaseCluster (#550).
• Omid test: use 1.1.2, update default port number and raise test timeout (#556).
• An invalid HBaseCluster doesn't cause the operator to stop functioning (#[575]).

Removed

• test: Remove ZooKeeper 3.8.4 (#558).

[24.7.0] - 2024-07-24

Added

• Added support for HBase 2.6.0 with the following changes (#506):

• Remove sed calls to replace KRB REALM in configuration. IMPORTANT: This means the operator will ONLY work with HBase versions that are compiled against Hadoop 3.x as of now (#531)

[24.3.0] - 2024-03-20

Added

• Support user authentication using Kerberos (#436).

• Use Snafu instead of thiserror (#438).

Removed

• [BREAKING] Removed legacy node selector on roleGroups (#438).
• Remove support for version 2.4.12 (#454).

Fixed

• Processing of corrupted log events fixed; If errors occur, the error messages are added to the log event (#511).

[23.11.0] - 2023-11-24

Added

• Default stackableVersion to operator version (#385).
• Configuration overrides for the JVM security properties, such as DNS caching (#389).
• Support PodDisruptionBudgets (#399).
• Support graceful shutdown (#402).
• Added support for version 2.4.17 (#403).

Changed

• vector 0.26.0 -> 0.33.0 (#382, #403).
• Use jmx_exporter soft link instead of hardcoded version (#403).

Fixed

• Fix Zookeeper hbase.rootdir when users point to discovery ConfigMap of ZookeeperCluster rather than ZNode. Print a warning in that case (#394).
• Default hbase.unsafe.regionserver.hostname.disable.master.reversedns to true, to ensure the names of RegionServers are resolved to their hostnames instead of IP addresses (#418).

Removed

• Removed support for 2.4.6, 2.4.8, 2.4.9, 2.4.11 (#403).

[23.7.0] - 2023-07-14

Added

• Generate OLM bundle for Release 23.4.0 (#350).
• Missing CRD defaults for status.conditions field (#360).
• Set explicit resources on all containers (#366, #378).
• Support podOverrides (#371, #373).

Changed

• Operator-rs: 0.40.2 -> 0.44.0 (#349, #366, #375).
• Use 0.0.0-dev product images for tests and examples (#351).
• Use testing-tools 0.2.0 (#351).
• Run as root group (#359).
• Added kuttl test suites (#369)

Fixed

• Fix missing quoting of env variables. This caused problems when env vars (e.g. from envOverrides) contained a whitespace (#356).
• Fix hbase.zookeeper.quorum to not contain the znode path, instead pass it via zookeeper.znode.parent (#357).
• Add hbase.zookeeper.property.clientPort setting, because hbase sometimes tried to access zookeeper with the (wrong) default port (#357).
• Fix test assert by adding variable quoting (#359).
• Increase the size limit of the log volume (#375).

[23.4.0] - 2023-04-17

Added

• Deploy default and support custom affinities (#322).
• OLM bundle files (#333).
• Extend cluster resources for status and cluster operation (paused, stopped) (#336).
• Cluster status conditions (#337).

Changed

• [BREAKING]: Consolidated top level configuration to clusterConfig (#334).
• [BREAKING] Support specifying Service type. This enables us to later switch non-breaking to using ListenerClasses for the exposure of Services. This change is breaking, because - for security reasons - we default to the cluster-internal ListenerClass. If you need your cluster to be accessible from outside of Kubernetes you need to set clusterConfig.listenerClass to external-unstable (#338).
• operator-rs 0.36.0 -> 0.40.2 (#334, #336, #339, #340).
• Use build_rbac_resources from operator-rs. This renames the hbase-sa ServiceAccount to hbase-serviceaccount (#340).

Fixed

• Avoid empty log events dated to 1970-01-01 and improve the precision of the log event timestamps (#339).

Removed

• [BREAKING]: Removed top level role/role group config (#334).

[23.1.0] - 2023-01-23

Added

• Log aggregation added (#294).

Changed

• [BREAKING] Use Product image selection instead of version. spec.version has been replaced by spec.image (#282).
• Updated stackable image versions (#275).
• operator-rs 0.24.0 -> 0.30.2 (#277, #293, #294).
• Set runAsGroup to 1000 rather than 0 (#283).
• Fixed: selector in role groups now works. It was not working before (#293)

[0.5.0] - 2022-11-07

Added

• Cpu and memory limits are now configurable (#245).
• Fix for Phoenix tests (#261)

[0.4.0] - 2022-09-06

Changed

• Use cli argument watch-namespace / env var WATCH_NAMESPACE to specify a single namespace to watch (#137).
• Writing a discovery config map containing hbase-site.xml with the hbase.zookeeper.quorum property (#163).

Changed

• operator-rs 0.12.0 -> 0.15.0 (#137, #153).
• Now using HDFS discovery config map instead of hdfs name node config map (#153)
• BREAKING: Consolidated CRD - discovery config maps now top level, removed several HbaseConfig options (can still be overridden) (#162):
  • hbaseManagesZk: defaults to false
  • hbaseClusterDistributed: defaults to true
• [BREAKING] Specifying the product version has been changed to adhere to ADR018 instead of just specifying the product version you will now have to add the Stackable image version as well, so version: 3.5.8 becomes (for example) version: 3.5.8-stackable0.1.0 (#179)

[0.2.0] - 2022-02-14

Added

• Reconciliation errors are now reported as Kubernetes events (#127).

Changed

• operator-rs 0.10.0 -> 0.12.0 (#127).
