> Project: HBase
> Issue Type: Improvement
> Components: shell
> Reporter: Liu Shaohui

>
> 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.
