-------------------------------------
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.
