Subject [jira] [Commented] (HADOOP-7748) Print exception message when failed to move to trash.
Date Fri, 14 Oct 2011 05:10:11 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13127275#comment-13127275
] 

Liyin Liang commented on HADOOP-7748:
-------------------------------------

When client fails to move a path to trash, the exception is retained, but the message is not
propagated to the new exception text, which becomes simply
rmr: Failed to move to trash: hdfs://namenode:9000/test/foo

The attached patch will change such message to include that of the nested exception, such
as
rmr: Failed to move to trash: hdfs://namenode:9000/test/foo error: org.apache.hadoop.security.AccessControlException:
org.apache.hadoop.security.AccessControlException: Permission denied: user=xxx, access=WRITE,
inode="test":hadoop:supergroup:rwxr-xr-x

Then it will be very helpful to diagnosis problems.
