Improve consistency of performance during heavy load
----------------------------------------------------
Key: HBASE-2981
URL: https://issues.apache.org/jira/browse/HBASE-2981
Project: HBase
Issue Type: Task
Components: regionserver
Reporter: Todd Lipcon
Currently when running load tests like YCSB, we experience periods of complete
cluster inactivity while all clients are blocked on a single region which is
unavailable.
As discussed recently on the list, we should brainstorm some ideas for how to
improve the situation: the goal here is to (a) minimize the amount of time when
a region is inaccessible, and (b) minimize the impact that one inaccessible
region has on other operations in the cluster.
