-----------------------------------

             Summary: Make hdfs ec -verifyClusterSetup command accept an 
erasure coding policy as a parameter
                 Key: HDFS-14188
                 URL: https://issues.apache.org/jira/browse/HDFS-14188
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: erasure-coding
    Affects Versions: 3.1.1
            Reporter: Kitti Nanasi
            Assignee: Kitti Nanasi


hdfs ec -verifyClusterSetup command verifies if there are enough data nodes and 
racks for the enabled erasure coding policies

I think it would be beneficial if it could accept an erasure coding policy as a 
parameter optionally. For example the following command would run the verify 
for only the RS-6-3-1024k policy.
{code:java}
hdfs ec -verifyClusterSetup -policy RS-6-3-1024k
{code}
