Masatake Iwasaki commented on HDFS-9689: ---------------------------------------- Thanks for working on this, [~liuml07]. Are other test processes still possible to bind the nn port between {{shutdownNameNode}} and {{createNameNode}} in {{MiniDFSCluster#restartNameNode}}? Though the patch narrows the time window of the port intercept. {code} shutdownNameNode(nnIndex); if (args.length != 0) { startOpt = null; } else { args = createArgs(startOpt); } NameNode nn = NameNode.createNameNode(args, info.conf); {code} > Test o.a.h.hdfs.TestRenameWhileOpen fails intermittently > --------------------------------------------------------- > > Key: HDFS-9689 > URL: https://issues.apache.org/jira/browse/HDFS-9689 > Project: Hadoop HDFS > Issue Type: Bug > Components: test > Affects Versions: 3.0.0, 2.8.0 > Reporter: Mingliang Liu > Assignee: Mingliang Liu > Attachments: HDFS-9689.000.patch > > > The test fails in recent builds, e.g. > https://builds.apache.org/job/PreCommit-HDFS-Build/14063/testReport/org.apache.hadoop.hdfs/TestRenameWhileOpen/ > and > https://builds.apache.org/job/PreCommit-HDFS-Build/14212/testReport/org.apache.hadoop.hdfs/TestRenameWhileOpen/testWhileOpenRenameToNonExistentDirectory/ > The *Error Message* is like: > {code} > Problem binding to [localhost:60690] java.net.BindException: Address already > in use; For more details see: http://wiki.apache.org/hadoop/BindException > {code} > and *Stacktrace* is: > {code} > java.net.BindException: Problem binding to [localhost:60690] > java.net.BindException: Address already in use; For more details see: > http://wiki.apache.org/hadoop/BindException > at sun.nio.ch.Net.bind0(Native Method) > at sun.nio.ch.Net.bind(Net.java:463) > at sun.nio.ch.Net.bind(Net.java:455) > at > sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:223) > at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:74) > at org.apache.hadoop.ipc.Server.bind(Server.java:469) > at org.apache.hadoop.ipc.Server$Listener.<init>(Server.java:695) > at org.apache.hadoop.ipc.Server.<init>(Server.java:2464) > at org.apache.hadoop.ipc.RPC$Server.<init>(RPC.java:958) > at > org.apache.hadoop.ipc.ProtobufRpcEngine$Server.<init>(ProtobufRpcEngine.java:535) > at > org.apache.hadoop.ipc.ProtobufRpcEngine.getServer(ProtobufRpcEngine.java:510) > at org.apache.hadoop.ipc.RPC$Builder.build(RPC.java:800) > at > org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.<init>(NameNodeRpcServer.java:392) > at > org.apache.hadoop.hdfs.server.namenode.NameNode.createRpcServer(NameNode.java:743) > at > org.apache.hadoop.hdfs.server.namenode.NameNode.initialize(NameNode.java:685) > at > org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:884) > at > org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:863) > at > org.apache.hadoop.hdfs.server.namenode.NameNode.createNameNode(NameNode.java:1581) > at > org.apache.hadoop.hdfs.MiniDFSCluster.createNameNode(MiniDFSCluster.java:1247) > at > org.apache.hadoop.hdfs.MiniDFSCluster.configureNameService(MiniDFSCluster.java:1016) > at > org.apache.hadoop.hdfs.MiniDFSCluster.createNameNodesAndSetConf(MiniDFSCluster.java:891) > at > org.apache.hadoop.hdfs.MiniDFSCluster.initMiniDFSCluster(MiniDFSCluster.java:823) > at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:482) > at > org.apache.hadoop.hdfs.MiniDFSCluster$Builder.build(MiniDFSCluster.java:441) > at > org.apache.hadoop.hdfs.TestRenameWhileOpen.testWhileOpenRenameToNonExistentDirectory(TestRenameWhileOpen.java:332) > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
