Review request for Ambari, Andrew Onischuk and Sumit Mohanty.
Bugs: AMBARI-17888
https://issues.apache.org/jira/browse/AMBARI-17888
Repository: ambari
Description
-------
A common method of addressing failed disks, which is to set unwritable
permissions on a directory such as /hadoop10 within the root filesystem.
Once mounted, the mounted filesystem will overlay the correct permissions
structure, allowing hdfs to write to the mounted disk.
In the case of a failed mount operation, the associated /hadoop10 directory
will be unwritable by hdfs.
However, Ambari will see the visible directory with incorrect permissions, and
"fix" the permissions back to a writable directory-- resulting in the datanode
filling the root partition of a machine.
We need to prevent ambari from changing permissions on YARN local and HDFS data
dirs.
