Subject [jira] Commented: (HDFS-938) Replace calls to UGI.getUserName() with UGI.getShortUserName()
Date Fri, 05 Feb 2010 20:38:28 GMT

    [ https://issues.apache.org/jira/browse/HDFS-938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12830284#action_12830284

Jakob Homan commented on HDFS-938:

For the 938 backport, looks like you got all the references in HDFS.  Since this patch is
being backported in three pieces, rather than the usual one, I have a question as to whether
it's correct that org/apache/hadoop/security/TestGroupMappingServiceRefresh.java is being
patched here?

> HADOOP-6526 details why UGI.getUserName() will not work to identify users. Until the
proposed UGI.getLocalName() is implemented, calls to getUserName() should be replaced with
the short name.
