The potential cause here could be several regions under "in transition" state for a long time. Those regions can be seen as offline from HBase Master UI. Due to high number of regions that are attempting to transition, HBase Master could timeout and will be unable to bring those regions back to online state.
Below are the steps to fix the hbck timeout problem:
-
Login to HDInsight HBase cluster using SSH.
-
Run 'hbase zkcli' command to connect with zookeeper shell.
-
Run 'rmr /hbase/regions-in-transition' or 'rmr /hbase-unsecure/regions-in-transition' command.
-
Exit from 'hbase zkcli' shell by using 'exit' command.
-
Open Ambari UI and restart Active HBase Master service from Ambari.
-
Monitor the HBase Master UI "region in transition" that section to make sure no region gets stuck.
