>
> 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.
