[jira] [Created] (HADOOP-16672) missing null check for UserGroupInformation while during IOSteam setup

Viraj Jasani created HADOOP-16672:
-------------------------------------

             Summary: missing null check for UserGroupInformation while during IOSteam setup
                 Key: HADOOP-16672
                 URL: https://issues.apache.org/jira/browse/HADOOP-16672
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 3.3.0
            Reporter: Viraj Jasani


While setting up IOStreams, we might end up with NPE if UserGroupInformation is null resulting from getTicket() call. Similar to other operations, we should add null check for ticket.doAs() call.
