I don't think it's a problem, but I'm inclined to upgrade both Hadoop and HBase at the same time if it is the combo that the community will support the most. I assume I should be able to stop HBase and HDFS, replace the HBase/Hadoop 0.20.0 binaries with 0.20.1 binaries on each node, and then start it all up again. Is that pretty much it?
