Ayush Saxena commented on HDFS-14188:
-------------------------------------
Thanx [~knanasi] for the patch!!!
Overall patch looks good. some minor comments ::
* Can we support to have multiple policies specified in the command
rather than having single?. If possible it shall be good if somebody wants to
give a check to more than one, since the operation is little heavy , It could
save some efforts.
* Regarding the Test. Do we need to put up two separate tests. It
seems the cluster setup is same in both. If no issue we can merge the two into
one only.
* I guess we should add the extended behavior of the API in the
document too.
> Make hdfs ec -verifyClusterSetup command accept an erasure coding policy as a

> 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}
