Subject CDH3B4 "fixes" permissions
Date Thu, 17 Mar 2011 23:00:20 GMT
Hi -


I just upgraded to CDH3B4. I noticed when I ran 'hadoop dfsadmin
-upgrade' that the logs on the datanodes showed that hadoop was "fixing"
the permissions of my dfs storage disks to "rwx------". I am just
wondering why it does this? I had been using a subdirectory of one of
the disks for hadoop.tmp.dir, and of course now the hadoop.tmp.dir
cannot be written.
