In fact, what causes the RegionMover to fail is this:
{code}
7/12/12 11:00:28 ERROR util.RegionMover: Error while unloading regions
java.lang.Exception: Server host1.example.com:22001 is not in list of online

> Probably this is the first of few issues found during some tests with
> RegionMover. After HBASE-13014 we ship the new RegionMover tool but it
> currently assumes that master will be hosting regions so it attempts to
> remove master from the list and that causes an issue similar to this:
