Sean Busbey resolved HBASE-7708. -------------------------------- Resolution: Won't Fix 0.92 is long since EOL, closing. > deprecated call in region_mover.rb causing high cpu utilization > --------------------------------------------------------------- > > Key: HBASE-7708 > URL: https://issues.apache.org/jira/browse/HBASE-7708 > Project: HBase > Issue Type: Improvement > Components: scripts > Reporter: Eric Edgeworth > Priority: Minor > > We noticed high CPU utilization while using region_mover.rb to unload > regions. Consulted with Stack, who suggested changing a line in > region_mover.rb from (the deprecated): > {code} > table = getTable(admin.getConfiguration(), r.getTableDesc().getName()) > {code} > to: > {code} > table = getTable(admin.getConfiguration(), r.getTableName()) > {code} > In our tests this dropped CPU utilization from ~200% over the course of the > unload to ~0.5% after startup, and allowed unload of ~200 regions to complete > in ~7 minutes instead of the original ~18 minutes, so the change seems to fix > the CPU utilization issue with no untoward side effects we could find. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
