Subject [jira] [Commented] (HADOOP-13715) Add isErasureCoded() API to FileStatus class
Date Tue, 21 Mar 2017 17:18:42 GMT

Steve Loughran commented on HADOOP-13715:
-----------------------------------------

toString here is something that surfaces in diagnostics logs more than anything else, especially
test failures....I don't think its one of the "Sacred" paths. It's extnded by the swift and
s3 subclasses, and nobody has complained about that.

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.
