-----------------------------------------

Merged with latest codebase, checked on live cluster and committed to
branch-2.1 and to trunk
> Ambari should not configure hbase.regionserver.global.memstore.upperLimit in
> HDP-2.3
> ------------------------------------------------------------------------------------
>
> Key: AMBARI-12224
> URL: https://issues.apache.org/jira/browse/AMBARI-12224
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Reporter: Myroslav Papirkovskyy
> Assignee: Myroslav Papirkovskyy
> Priority: Critical
> Fix For: 2.1.0
>
>
> HBase has deprecated {{hbase.regionserver.global.memstore.upperLimit}} and
> {{hbase.regionserver.global.memstore.lowerLimit}} for HDP-2.3 in favor of
> {{hbase.regionserver.global.memstore.size}} and
> {{hbase.regionserver.global.memstore.size.lower.limit}}.
> The slider called "% of RegionServer Allocated to Write Buffers" sets
> {{hbase.regionserver.global.memstore.size}}, while
> {{hbase.regionserver.global.memstore.upperLimit}} is in the advanced
> configuration section. This leaves two bugs:
> - In HDP-2.2, the slider has no affect since HBase basically ignores the
> parameter.
> - In HDP-2.3 the value set by the slider also has no affect since the
> deprecated values set take precedence.
> One solution is to get rid of
> {{hbase.regionserver.global.memstore.upperLimit}} and
> {{hbase.regionserver.global.memstore.lowerLimit}} in advanced settings in
> Ambari, and make the slider configuration to use
> {{hbase.regionserver.global.memstore.upperLimit}} in HDP-2.2 and
> {{hbase.regionserver.global.memstore.size}} in HDP-2.3. Rolling upgrade can
> convert these settings.
