Re: Accumulo / Hadoop version compatibility matrix
Terry P. 2013-05-08, 23:44
Uh oh ... I saw in the README that Accumulo 1.4.2 had been tested with
Hadoop 0.20.2, which is the version found in CDH3u5.  I didn't see anything
that called out issues with CDH3u4+ in the README (in fact neither Cloudera
nor cdh are found in the readme anywhere).

So I'm running Accumulo 1.4.2 on CDH3u5 on an 8-node cluster which I was
intending to deliver as a Dev environment this Friday.  I did not build
Accumulo, I'm using the binary distribution.

One reason I chose cdh3u5 was because it's "approved" FOSS software.  No
Hadoop 1.1.x is approved (yet), and our approval chain is lengthy.

Did I just make a colossal error?  What exactly "doesn't work" with
cdh3u4+?  How bad of shape am I in?  Data loss bad?
