Review Request 30029: Configs: Editing HBase Region Server
Configuration Parameters

Review request for Ambari and Dmitro Lisnichenko.
Bugs: AMBARI-9195
https://issues.apache.org/jira/browse/AMBARI-9195
Repository: ambari
Description
-------
The HBase block cache size parameter is editable through Ambari. But HBase
verifies whether the sum of the value specified for hfile.block.cache.size and
hbase.regionserver.global.memstore.upperLimit doesn't exceed 0.8 when it
starts. We would want to make the memstore variables
(hbase.regionserver.global.memstore.upperLimit and
hbase.regionserver.global.memstore.upperLimit) editable or at least adjust
these values automatically if the user changes the block cache size (may not
be a preferable option).
Diffs
