Description

All day it has been timing out. Its a medium test. There is a bit in the middle where we are hung up for a minute or more:

2018-02-01 23:01:02,471 DEBUG [Time-limited test] hfile.HFile$WriterFactory(336): Unable to set drop behind on /testptch/hbase/hbase-server/target/test-data/6a153924-7f81-4008-ac7e-d0e69384655e/data/default/CompactionCacheOnWrite/6dd6ed35f3b6090bd8d04ed21d687424/.tmp/myCF/c0387b09f82840ab9e636faf5cf02d2d

...

I've seen this a few times. The test takes 100seconds locally.

Let me try changing it to type. If that doesn't work, will be back.
