Subject Re: DFS Permissions on Hadoop 2.x
Date Tue, 18 Jun 2013 22:24:43 GMT
Hi Chris,

This is while running a MR job. Please note the job is able to write files
to "/mapred" directory and fails on EXECUTE permissions. On digging in some
more, it looks like the failure occurs after writing to
"/mapred/history/done_intermediate".

Here is a more detailed stacktrace.
