h2. What happened After setting {{{}dfs.namenode.replication.min=12396{}}}, running test {{org.apache.hadoop.hdfs.server.namenode.ha.TestHarFileSystemWithHA#testHarUriWithHaUriWithNoPort}} results in a {{{}NullPointerException{}}}. h2. Where's the bug In the test {{{}org.apache.hadoop.hdfs.server.namenode.ha.TestHarFileSystemWithHA#testHarUriWithHaUriWithNoPort{}}}: {noformat} } finally { cluster.shutdown(); }{noformat} the test tries to shutdown the cluster for cleaning up. However, if the cluster is not generated and cluster=null, the NPE would conceal other failures. h2. How to reproduce # Set {{dfs.namenode.replication.min=12396}} # Run {{org.apache.hadoop.hdfs.server.namenode.ha.TestHarFileSystemWithHA#testHarUriWithHaUriWithNoPort}} and the following exception should be observed: {noformat} java.lang.NullPointerException at org.apache.hadoop.hdfs.server.namenode.ha.TestHarFileSystemWithHA.testHarUriWithHaUriWithNoPort(TestHarFileSystemWithHA.java:60){noformat} For an easy reproduction, run the reproduce.sh in the attachment.
