> When the region server R1 and data node D1 running in the same machine and
> let's assuem this machine pub into repair,
> the master will try to reassign all the regions in the region server to other
> region server R2. But at that time, the name node hasn't figure out the bad
> data node D1.
> So the region server R2 will try to open the region from the D1, which will
> failed and retried. Then the master believes it took TOO LONG to open this
> region, so it reassign to R3...
> The story continues until the name node figure out the bad datanode D1 and
> finally region server Rn opens the region and do the compaction for the store
> file.
> All previous region servers cannot the region later and find the file doesn't
> exist since it has been compacted.
> So the solution is that when region has been OPENING for too long, the master
> should not reassign region.
