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:
