Ayush Saxena commented on HDFS-14602:
-------------------------------------
If you try to do it via API, you will get NULL only, as the Namenode reports on
account of replication policy returns NULL only, For the shell command it is a
polished line after checking NULL.
It doesn't tell it has Replication policy set, It just tells the EC Policy is
null in words.
{noformat}
hdfs ec -getPolicy -path /dir/subdir
RS-6-3-1024k
hdfs ec -setPolicy -path /dir/subdir -replicate
Set replication erasure coding policy on /dir/subdir
hdfs ec -getPolicy -path /dir/subdir
The erasure coding policy of /dir/subdir is unspecified
{noformat}
and We can't change this behaviour, as Xiao Chen mentioned in HDFS-13774 due
to compatibility reasons. Try giving a check to the discussion out there.
