> 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}
