      Description

      I set hbase.systemtables.compacting.memstore.type to NONE but it seems like in-memory is still on. My table looks like this:

      Table ycsb is ENABLED
      ycsb
      COLUMN FAMILIES DESCRIPTION
      {NAME => 'family', VERSIONS => '1', EVICT_BLOCKS_ON_CLOSE => 'false', NEW_VERSION_BEHAVIOR => 'false', KEEP_DELETED_CELLS => 'FALSE', CACHE_DATA_ON_WRITE => 'false', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', MIN_VERSIONS => '0', REPLICATION_SCOPE => '0', BLOOMFILTER =
      > 'ROW', CACHE_INDEX_ON_WRITE => 'false', IN_MEMORY => 'false', CACHE_BLOOMS_ON_WRITE => 'false', PREFETCH_BLOCKS_ON_OPEN => 'false', COMPRESSION => 'NONE', BLOCKCACHE => 'true', BLOCKSIZE => '65536'}
      

      Looks like table doesn't have it on either (IN_MEMORY_COMPACTION doesn't show in the above).
