Eli Collins resolved HDFS-3933. ------------------------------- Resolution: Duplicate Now that we can see the root cause, this is a dupe of HDFS-3936. {noformat} 2012-09-13 18:22:07,575 FATAL [main] hdfs.MiniDFSCluster (MiniDFSCluster.java:shutdown(1355)) - Test resulted in an unexpected exit org.apache.hadoop.util.ExitUtil$ExitException: Fatal exception with message null stack trace java.lang.NullPointerException at org.apache.hadoop.hdfs.server.blockmanagement.BlocksMap.getBlockCollection(BlocksMap.java:101) at org.apache.hadoop.hdfs.server.blockmanagement.BlockManager.computeReplicationWorkForBlocks(BlockManager.java:1132) at org.apache.hadoop.hdfs.server.blockmanagement.BlockManager.computeReplicationWork(BlockManager.java:1107) at org.apache.hadoop.hdfs.server.blockmanagement.BlockManager.computeDatanodeWork(BlockManager.java:3061) at org.apache.hadoop.hdfs.server.blockmanagement.BlockManager$ReplicationMonitor.run(BlockManager.java:3023) at java.lang.Thread.run(Thread.java:662) {noformat} > Unclean exit in ReplicationMonitor#run occasionally causes tests to fail > ------------------------------------------------------------------------- > > Key: HDFS-3933 > URL: https://issues.apache.org/jira/browse/HDFS-3933 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.0.0-alpha > Reporter: Eli Collins > Assignee: Eli Collins > > I've seen the following in jenkins jobs for TestHadoopArchives and > TestBlockTokenWithDFS. We're not getting the initial ExitException thrown by > ReplicationMonitor, just the log of the ExitException in MiniDFSCluster > shutdown. Looks like the ExitException has no message so the throwable that > resulted in the ExitException has no message, in which case it would be > useful to capture the whole stacktrace of the throwable. > {noformat} > 2012-09-12 18:22:08,370 FATAL [main] hdfs.MiniDFSCluster > (MiniDFSCluster.java:shutdown(1355)) - Test resulted in an unexpected exit > org.apache.hadoop.util.ExitUtil$ExitException > at org.apache.hadoop.util.ExitUtil.terminate(ExitUtil.java:86) > at org.apache.hadoop.util.ExitUtil.terminate(ExitUtil.java:104) > at > org.apache.hadoop.hdfs.server.blockmanagement.BlockManager$ReplicationMonitor.run(BlockManager.java:3031) > at java.lang.Thread.run(Thread.java:662) > {noformat} -- This message is automatically generated by JIRA.
