Subject [jira] [Created] (HBASE-19756) Master NPE during completed failed proc eviction
Date Wed, 10 Jan 2018 23:00:07 GMT
Thiruvel Thirumoolan created HBASE-19756:
--------------------------------------------

             Summary: Master NPE during completed failed proc eviction
                 Key: HBASE-19756
                 URL: https://issues.apache.org/jira/browse/HBASE-19756
             Project: HBase
          Issue Type: Bug
    Affects Versions: 1.3.1, 1.4.0
            Reporter: Thiruvel Thirumoolan


When procedures like Create table fails due to say AccessDeniedException, then a rollback
procedure is created. When the rollback is being cleaned up, it results in an NPE because
those nonce procs aren't persisted

Stack trace when this happens:

java.lang.NullPointerException
