Steve Loughran resolved HADOOP-12840. ------------------------------------- Resolution: Duplicate duplicate of HADOOP-10315 > UGI to log@ debug stack traces when failing to find groups for a user > --------------------------------------------------------------------- > > Key: HADOOP-12840 > URL: https://issues.apache.org/jira/browse/HADOOP-12840 > Project: Hadoop Common > Issue Type: Sub-task > Components: security > Affects Versions: 2.8.0 > Reporter: Steve Loughran > Priority: Minor > > If {{UGI.getGroupNames()}} catches an IOE raised by > {{groups.getGroups(getShortUserName())}} then it simply logs @ debug "No > groups available for user". The text from the caught exception and stack > trace are not printed. > One IOException raised is the explicit "user not in groups" exception, but > there could be other causes too —if that happens the entire problem will be > missed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
