Subject [jira] [Commented] (HADOOP-13715) Add isErasureCoded() API to FileStatus class

--------------------------------------

Hi Manoj, looks real close, thanks for revving. Any reason you chose to write a new test rather
than extending BaseTestHttpFSWith? That's where we test the ACL bit and encrypted bit, so
seems like it'd be easy to add ec bit support there too. The base test covers some different
combinations as well.

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.
