Description

When meta region is moved during region split, the spitting region may become RIT(Region in Transition) for 20 minutes. And then the RegionServer has the RIT will fail. We are facing the issue during RegionServer rolling restart on HBase 1.4.13. I found that HBase 1.7.1 has the same issue, too. It is OK on HBase 2.4.12.

This is the fix.
