-----------------------------------
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.
