Subject [jira] [Commented] (HADOOP-12547) Remove hadoop-pipes
Date Wed, 04 Nov 2015 15:50:27 GMT

Allen Wittenauer commented on HADOOP-12547:
-------------------------------------------

bq. If we are going to keep this, I would like to see some unit tests, documentation, and
actual maintenance.

This pretty much sums up my feelings towards libwebhdfs as well, yet we're keeping it around
because someone, somewhere might have fixed the compilation issues (hint: it's still broken
in this recent 2.6 release) and is actually using it.

I see no reason to remove pipes if we're not also removing libwebhdfs.  The reasons to remove
are pretty much identical, but at least pipes a) has compiled for most of its lifetime and
b) we have evidence that people are actually looking at it.  

So from where I stand, they either both go or both stay.

> Development appears to have stopped on hadoop-pipes upstream for the last few years,
aside from very basic maintenance.  Hadoop streaming seems to be a better alternative, since
it supports more programming languages and is better implemented.
> There were no responses to a message on the mailing list asking for users of Hadoop pipes...
and in my experience, I have never seen anyone use this.  We should remove it to reduce our
maintenance burden and build times.
