Wei-Chiu Chuang commented on HDFS-14188:
----------------------------------------
Thanks for the updated patch.
One question: is "reserOutputs()" a typo? Should it be "resetOutputs()"?
{quote}-verifyClusterSetup -policy <policyName>...<policyName>
{quote}
This is unfortunately not entirely accurate.
Running this command, I ended up with error "-verifyClusterSetup: Too many
arguments"
In fact, you would need to double quote multiple policy names. For example,
{quote}-verifyClusterSetup -policy "RS-3-2-1024k RS-10-4-1024"
{quote}
Otherwise arguments won't parse correctly.

>
> 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}
