> 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.
