Subject RE: Hadoop 0.21 support
Date Mon, 20 Dec 2010 23:58:27 GMT
Dmitry-

Thanks for looking into this.  

HADOOP-2141 is indeed what we need.  I am a bit confused - the JIRA page
(https://issues.apache.org/jira/browse/HADOOP-2141) shows it was included in
Hadoop 0.21, but CDH3b3 appears to be based on 0.20 (shown as
hadoop-0.20.noarch in their yum repo).  Does Cloudera typically backport
features like this?

Regardless, I'll install CDH3b3 and use it.  Thanks for the tip!

-Ben

Also , just in case if you are talking about  HADOOP-2141, it _is_ included
in CDH3b3, and i did verify before that CDH3b3 compiles with Mahout.

Thanks.
