Description

The result of getStoragePolicy command is always 'unspecified' even we has set a StoragePolicy on a directory.But the real placement of blocks is correct.
The result of fsck is not correct either.

$ hdfs storagepolicies -setStoragePolicy -path /tmp/cold  -policy COLD
Set storage policy COLD on /tmp/cold
$ hdfs storagepolicies -getStoragePolicy -path /tmp/cold
The storage policy of /tmp/cold is unspecified

$ hdfs fsck -storagepolicies /tmp/cold
Blocks NOT satisfying the specified storage policy:
Storage Policy                  Specified Storage Policy      # of blocks       % of blocks
ARCHIVE:4(COLD)                     HOT                           5              55.5556%
ARCHIVE:3(COLD)                     HOT                           4              44.4444%
