--------------------------------
Hi [~Sammi] and [~tasanuma0829], yes this Jira is duplicate of HDFS-7717 .
How about close this one, and I will reassign HDFS-7717 to you, Sammi?

> Set erasure coding policy to an existing 3x replication file, or change the
> current existing erasure coding policy of an existing file to another erasure
