Description

I was trying to find cause for test failure in https://builds.apache.org/job/PreCommit-HBASE-Build/9036//testReport/org.apache.hadoop.hbase.snapshot/TestSecureExportSnapshot/testExportRetry/ :

org.apache.hadoop.hbase.snapshot.HBaseSnapshotException: org.apache.hadoop.hbase.snapshot.HBaseSnapshotException: Snapshot { ss=emptySnaptb0-1395177346656 table=testtb-1395177346656 type=FLUSH } had an error.  Procedure emptySnaptb0-1395177346656 { waiting=[] done=[] }

However, it is not clear which region caused the verification to fail.
I searched for log from balancer but found none.

The exception message should include region name which caused the verification to fail.
