Summary: Enable automagically tweaking memstore and blockcache
sizes
Key: HBASE-11206
URL: https://issues.apache.org/jira/browse/HBASE-11206
Project: HBase
Issue Type: Task
Reporter: stack
Assignee: stack
Fix For: 0.99.0
HBASE-5349
"Automagically tweak global memstore and block cache sizes based on workload"
adds a nice new feature. It is off by default. Lets turn it on for 0.99.
Liang Xie is concerned that automatically shifting blockcache and memstore
sizes could wreck havoc w/ GC'ing in low-latency serving situation -- a valid
concern -- but lets enable this feature in 0.99 and see how it does. Can
always disable it before 1.0 if a problem.
