> In old Ambari versions, in HBase config area, there is a slider to change this config (Write buffer cache) along with the slider for changing read cache %.
> We have noticed issue in 2.7.3
> I checked master branch and there also issue seems to be there.
> In https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/stacks/BIGTOP/3.2.0/services/HBASE/themes/theme.json,
> there is a configuration-layout placement and this config entry is missing there.
> As this is a default added/considered config by Ambari , we wont be able to set/change this value using the Custom configs pane as well.
> So always end up using default 40% what HBase internally having
