Region IPC operations should be high priority
---------------------------------------------
Key: HBASE-3401
URL: https://issues.apache.org/jira/browse/HBASE-3401
Project: HBase
Issue Type: Bug
Components: regionserver
Affects Versions: 0.90.1
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Fix For: 0.90.1
I manufactured an imbalanced cluster so one region server had 300 regions and
the others had very few. I then ran balancer while hitting the high-load region
server with YCSB. I observed that the rate of load shedding was VERY slow since
the closeRegion IPCs were getting stuck at the back of the IPC queue.
All of these important master->RS RPC calls should be set to high priority.
