I am curious if anyone has upgraded their Accumulo clouds Hadoop version from 0.20.2  to CDH3  which is based off of a version of 0.20.2.  Can you just replace one version with another on an active cloud?

Anyone tried this?

The upgrade *should* be relatively painless.

The only thing to note is that you will need to recompile Accumulo
against the correct CDH3 artifacts from >=CDH3u4.

With Accumulo 1.5.0 this can be done by specifying
-Dhadoop.version=0.20.2-cdh3u5 and -Dzookeeper.version=3.3.5-cdh3u5 when
you `mvn package -Passemble`. With Accumulo 1.4.x, you'll have to update
the dependencies in the pom yourself.

This isn't specific to Accumulo, but if you're coming from a version of
hadoop that uses only the hadoop user, you should be aware that CDH3u5
expects hdfs and mapred users. There's some additional resources available

I don't think that CDH3u5 requires a recompile, that's only the case for
CDH4/hadoop 0.23/hadoop2.
