stack reopened HBASE-14807:
---------------------------
Looks like its possible for the test to run in a manner not expected. See
recent fail on master build:
https://builds.apache.org/view/H-L/view/HBase/job/HBase-Trunk_matrix/jdk=latest1.8,label=Hadoop/lastCompletedBuild/testReport/
where the latch in FSHLog goes into place only after all the drama has passed.
Deal with it.
