Subject [jira] [Created] (HBASE-12434) Add a command to compact all the region in a regionserver
Date Thu, 06 Nov 2014 04:27:34 GMT
Liu Shaohui created HBASE-12434:
-----------------------------------

             Summary: Add a command to compact all the region in a regionserver
                 Key: HBASE-12434
                 URL: https://issues.apache.org/jira/browse/HBASE-12434
             Project: HBase
          Issue Type: Improvement
          Components: shell
            Reporter: Liu Shaohui
            Assignee: Liu Shaohui
            Priority: Minor
             Fix For: 2.0.0


When adding 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.
