Er, to I made a mistake in the above question ; the issue is not so much the major compaction but rather that during restart (as nodes go up / down), Hadoop and HBase attempt to rebalance blocks and regions, causing unnecessary movement. So what I'm actually looking for is a way to avoid the balancing for the duration of the restart, which would avoid the need for major compaction afterwards.
