             Summary: Enable automagically tweaking memstore and blockcache sizes
                 Key: HBASE-11206
                 URL: https://issues.apache.org/jira/browse/HBASE-11206

          Issue Type: Task

             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.
