      Added a new config 'hbase.systemtables.compacting.memstore.type" for the system tables. By default all the system tables will have 'NONE' as the type and so it will be using the default memstore by default.

    Description

      HBASE-18992 brought this topic. Currently META is also using Compacting Memstore. We should decide if system tables can go with Default memstore only.
