Andrew Wang commented on HADOOP-13715:
--------------------------------------

LGTM +1, committed to trunk, thanks for the great contribution Manoj!

Do you mind checking if we have JIRAs filed for these flaky tests? Precommit has been really
suffering lately. It might be interesting to dive into the EC related one.

I would like to add a new API {{isErasureCoded()}} to {{FileStatus}} so that tools and downstream
applications can tell if it needs to treat a file differently.
> Hadoop tools that can benefit from this effort include: distcp and teragen/terasort.
> Downstream applications such as flume or hbase may also benefit from it.
