Subject [jira] [Commented] (HBASE-13525) Update test-patch to leverage rewrite in Hadoop
Date Tue, 21 Apr 2015 21:13:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14505782#comment-14505782

Allen Wittenauer commented on HBASE-13525:
------------------------------------------

One of my unstated goals with HADOOP-11746 was for it to be a mostly drop-in replacement for
any project currently using the older bits. (A quick pass through most of the ecosystem reveals
that the majority are using some form of it or another).  The plug-in capabilities certainly
make it easier to add custom stuff, but it's a lot harder to fix some assumptions made about
the source tree layout and maven usage (of course).

(Weirdly, this is the second time that having some generic bits that the entire ecosystem
could leverage has come up with some major rewrite I've undertaken. Roman suggested pulling
the base shell scripts out of Hadoop and forming a completely separate project!)

Anyway, for better or worse, HBase probably has the most customized out of all of them, based
upon my quick pass through.  I'll try to offer guidance where I can.  It'll be interesting
to see what does/doesn't work, especially with the new framework. The biggest one I'm worried
about are the backward compatibility bits.  I *hope* override works there, but I haven't had
a chance to actually test that part.... ;)

> Once HADOOP-11746 lands over in Hadoop, incorporate its changes into our test-patch.
Most likely easiest approach is to start with the Hadoop version and add in the features we
have locally that they don't.
