Description

 Erasure coding: "hdfs ec -getPolicy"" is not retrieving policy details when the special REPLICATION policy set on the directory

Steps :-

 - Create a directory "testEC"

• Get the EC policy for the directory [Received message as : "The erasure coding policy of /testEC is unspecified" ]
• Enable any Erasure coding policy like "XOR-2-1-1024k"
• Set the EC Policy on the Directory
• Get the EC policy for the directory [Received message as : "XOR-2-1-1024k" ]
• Now again set the EC Policy on the directory as "replicate" special REPLICATION policy
• Get the EC policy for the directory [Received message as : "The erasure coding policy of /testEC is unspecified" ]
  The policy is being set for the Directory ,but while retrieving policy details its throwing error as
  policy for the directory is unspecified which is wrong behavior
