> 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.
