Summary: Configs: Editing HBase Region Server Configuration
Parameters
Key: AMBARI-9195
URL: https://issues.apache.org/jira/browse/AMBARI-9195
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 2.0.0
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).
