Nicolas Liochon commented on HADOOP-12450: ------------------------------------------ +1 (non binding)... > UserGroupInformation should not log at WARN level if no groups are found > ------------------------------------------------------------------------ > > Key: HADOOP-12450 > URL: https://issues.apache.org/jira/browse/HADOOP-12450 > Project: Hadoop Common > Issue Type: Improvement > Components: security > Reporter: Elliott Clark > Assignee: Elliott Clark > Priority: Minor > Attachments: HADOOP-12450-v1.patch, HADOOP-12450-v2.patch > > > HBase tries to get the groups of a user on every request. That user may or > may not exist on the box running Hadoop/HBase. > If that user doesn't exist currently Hadoop will log at the WARN level > everytime. This leads to gigs of log spam and serious GC issues. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
