Hi,
Can "yarn.app.mapreduce.am.staging-dir" be set to use Linux shared mount

mapred-site.xml
yarn.app.mapreduce.am.staging-dir
file:/share_mnt/tmp

Please help!
* FYI, localFS here is shared disk mounted in CentOS.*
I have also tired to use another mount point which is of ext4 format, I get
similar error as
*/tmp/hadoop-yarn/staging/user_a/.staging/ is changed to 700 which is owned
by user_a thus yarn cannot read it.*
Any idea?
