dhruba borthakur commented on HDFS-167: --------------------------------------- It appears that you already made HDFS-514 to check in only the changes to DFSClient.namenode. Thanks. > DFSClient continues to retry indefinitely > ----------------------------------------- > > Key: HDFS-167 > URL: https://issues.apache.org/jira/browse/HDFS-167 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Derek Wollenstein > Assignee: Bill Zeller > Priority: Minor > Attachments: hdfs-167-4.patch, hdfs-167-5.patch > > > I encountered a bug when trying to upload data using the Hadoop DFS Client. > After receiving a NotReplicatedYetException, the DFSClient will normally > retry its upload up to some limited number of times. In this case, I found > that this retry loop continued indefinitely, to the point that the number of > tries remaining was negative: > 2009-03-25 16:20:02 [INFO] > 2009-03-25 16:20:02 [INFO] 09/03/25 16:20:02 INFO hdfs.DFSClient: Waiting for > replication for 21 seconds > 2009-03-25 16:20:03 [INFO] 09/03/25 16:20:02 WARN hdfs.DFSClient: > NotReplicatedYetException sleeping > /apollo/env/SummaryMySQL/var/logstore/fiorello_logs_2009 > 0325_us/logs_20090325_us_13 retries left -1 > The stack trace for the failure that's retrying is: > 2009-03-25 16:20:02 [INFO] 09/03/25 16:20:02 INFO hdfs.DFSClient: > org.apache.hadoop.ipc.RemoteException: > org.apache.hadoop.hdfs.server.namenode.NotReplicated > YetException: Not replicated yet:<filename> > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getAdditionalBlock(FSNamesystem.java:1266) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.hdfs.server.namenode.NameNode.addBlock(NameNode.java:351) > 2009-03-25 16:20:02 [INFO] at > sun.reflect.GeneratedMethodAccessor19.invoke(Unknown Source) > 2009-03-25 16:20:02 [INFO] at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > 2009-03-25 16:20:02 [INFO] at > java.lang.reflect.Method.invoke(Method.java:597) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.ipc.RPC$Server.call(RPC.java:481) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.ipc.Server$Handler.run(Server.java:894) > 2009-03-25 16:20:02 [INFO] > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.ipc.Client.call(Client.java:697) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.ipc.RPC$Invoker.invoke(RPC.java:216) > 2009-03-25 16:20:02 [INFO] at $Proxy0.addBlock(Unknown Source) > 2009-03-25 16:20:02 [INFO] at > sun.reflect.GeneratedMethodAccessor2.invoke(Unknown Source) > 2009-03-25 16:20:02 [INFO] at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > 2009-03-25 16:20:02 [INFO] at > java.lang.reflect.Method.invoke(Method.java:597) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:82) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:59) > 2009-03-25 16:20:02 [INFO] at $Proxy0.addBlock(Unknown Source) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.locateFollowingBlock(DFSClient.java:2814) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.nextBlockOutputStream(DFSClient.java:2696) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.access$2000(DFSClient.java:1996) > 2009-03-25 16:20:02 [INFO] at > org.apache.hadoop.hdfs.DFSClient$DFSOutputStream$DataStreamer.run(DFSClient.java:2183) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
