Similar test failure occurred in master JDK 8 build as well (https://builds.apache.org/job/HBase-TRUNK_matrix/839/jdk=latest1.8,label=yahoo-not-h2/testReport/org.apache.hadoop.hbase.regionserver/TestDateTieredCompactionPolicy/negativeForMajor/).

Since TestDateTieredCompactionPolicy is a small test, its failure prevented large tests from running.
