Re: hbase-master-server slept
First,
In the world of Hadoop, if it ain't broke don't fix it, may not be the best advice.
HBase is still evolving at a good pace and you want to be closer to the latest releases.
CDH4 is stable so that I would agree that going to CDH4 would be best.

Second.
You are running this as a single machine within the VM.

What does the hardware look like?
Number of cores, physical or virtual ?
How much memory?

What type of disks and where are they?
( attached or SAN?)
Sent from a remote device. Please excuse any typos...
