Description

Occasionally we see errors like this that doesn't really give much clue what went wrong.

2024-04-22 08:08:02,026 ERROR org.apache.hadoop.hbase.master.HMaster: ***** ABORTING master ccycloud-7.ozn-hb973chf3oz.xyz,22001,1713770648404: Log rolling failed *****

        at org.apache.hadoop.hbase.wal.AbstractWALRoller.run(AbstractWALRoller.java:211)

In this case, it was due to a time out exception. It would be helpful to make the log message more friendly.
