> I've observed {{TestFileTruncate#setup()}} function has to be improved by making it more
independent. Presently if any of the snapshots related test failures will affect all the subsequent
unit test cases. One such error has been observed in the [Hadoop-Hdfs-trunk-2163|https://builds.apache.org/job/Hadoop-Hdfs-trunk/2163/testReport/junit/org.apache.hadoop.hdfs.server.namenode/TestFileTruncate/testTruncateWithDataNodesRestart]
