> When adding a new regionserver to the hbase cluster, the data locality of the 
> regions in the new regionserver is very low. Most read hdfs requests from 
> these regions are remote read, not local read. So, the latency of read 
> request to these regions is not stable. 
> Usually we can compact all the regions in the new regionserver to improve the 
> data locality in offpeak.
> So we add a command: compact_rs in hbase shell.
