Manoj Govindassamy updated HADOOP-13715:
----------------------------------------
Attachment: HADOOP-13715.06.patch
Thanks for the review [~andrew.wang]. Please take a look at v06 patch with
following comment addressed.
bq. Could we rename the JSON field "erasureBit" to "ecBit" for conciseness?
This will make the wire representation a little more compact. Also rename
ERASURE_CODED_BIT_JSON to EC_BIT_JSON to match as well.
Sure, made the necessary changes for above.
> Add isErasureCoded() API to FileStatus class

> 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.
