We have taken the approach of graceful stop of the RegionServer in maintenance. Then restarting the DataNode. Once it has registered and back online we start the RegionServer and move it's regions back. We do not compact before or after the operation since it takes a short period of time, and minor compactions will regain the small amount of locality lost during the maintenance operation.
I believe it's doubtful that he Hadoop project itself will release an official cluster management / operations framework. So we built a lot of this ourselves.
