Description

TestCacheOnWrite passes locally but has been flaking in 0.98 builds on Jenkins, most recently https://builds.apache.org/job/HBase-0.98/878/

The test takes a long time to execute (338.492 sec) and is resource intensive (216 tests). Neither of these characteristics endear it to Jenkins.

When I ran this unit test on a macbook after a minute the fan was running so fast I thought it would take flight.
