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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
