Daniel Templeton commented on HDFS-13998:
-----------------------------------------

The safest answer is to add another CLI option.  I also think it's clearer.  I 
find {{hdfs ec -setPolicy -path /EC}} to be strange syntax.  Let's set the 
policy but not say to what!  Huh?

> ECAdmin NPE with -setPolicy -replicate

> HDFS-13732 tried to improve the output of the console tool. But we missed the 
> fact that for replication, {{getErasureCodingPolicy}} would return null.
> This jira is to fix it in ECAdmin, and add a unit test.
