Subject [jira] [Commented] (HDFS-4506) HDFS short circuit fails non-transparently when user does not have unix permissions
Date Mon, 18 Feb 2013 04:31:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13580406#comment-13580406

meng gong commented on HDFS-4506:
---------------------------------

I can't reproduce this issue with source code of branch-1.
The FileNotFoundException will be catched as an IOException.
Can you give out more logs or environment details?

> We found a case, where if the short circuit user name is configured correctly, but the
user does not have enough permissions in unix, DFS operations fails with IOException, rather
than silently failing over through datanode.
