----------------------------------
Hi [~andrew.wang], the patch looks overall great to me.
One style, this can be merge into one line.

fs.enableErasureCodingPolicy(
ecPolicy.getName());

An alternative is we keep RS(6,3) policy, reduce the "stripesPerBlock" from "4"
to "2", theoretically thus can reduce 50% time compared with RS(6,3) to RS(3,2)
> Reduce runtime of TestWriteReadStripedFile

> This test takes a long time to run since it writes a lot of data, and
> frequently times out during precommit testing. If we change the EC policy
> from RS(6,3) to RS(3,2) then it will run a lot faster.
