    Description

      The TestMultiColumnScanner is easy to be timeout, you can see HBASE-21517. In my localhost, when I set the parameters to be

      { Compression.Algorithm.NONE, BloomType.ROW, false }

      , it took about 5 seconds. but if I set the parameters to be

      { Compression.Algorithm.NONE, BloomType.ROWCOL, false }

      , it would take about 45 seconds, which means ROWCOL cost much more time than ROW.

      Need to find out what's wrong with this ut.
