Repairing a cluster with HBCK2

HBCK2 is the repair tool for Apache HBase clusters. It is contained in the hbase-operator-tools. The hbase-operator-tools are installed in the Docker image provided by Stackable in the directory /stackable/hbase-operator-tools/. HBCK2 can be easily executed via the wrapper script hbck2.

For instance, if you followed the First steps then you have a cluster called simple-hbase running. Let us assume that the HBase user interface reports unknown RegionServers, then you can schedule the ServerCrashProcedure for these RegionServers by applying the following Job:

--- apiVersion: batch/v1 kind: Job metadata: name: hbck2-recover-unknown spec: template: spec: containers: - name: hbck2 image: docker.stackable.tech/stackable/hbase:2.4.17-stackable0.0.0-dev volumeMounts: - name: hbase-config mountPath: /stackable/conf env: - name: HBASE_CONF_DIR value: /stackable/conf - name: HADOOP_CONF_DIR value: /stackable/conf command: - hbck2 args: - recoverUnknown volumes: - name: hbase-config projected: sources: - configMap: name: simple-hdfs - configMap: name: simple-hbase-master-default
