Hi,all I am running hadoop 0.23 on 5 nodes.
I could run any YARN application or Mapreduce Job on this cluster before. But, after I changed Resourcemanager Node from node4 to node5, when I run applications (I have modified property referenced in configure file), map and reduce process will hang up at 0% until I killed the application. I don't know why. terminal output: bin/hadoop jar hadoop-mapreduce-examples-0.23.0.jar wordcount /share/stdinput/1k /testread/hao 11/12/20 20:20:29 INFO mapreduce.Cluster: Cannot pick org.apache.hadoop.mapred.LocalClientProtocolProvider as the ClientProtocolProvider - returned null protocol 11/12/20 20:20:29 INFO ipc.YarnRPC: Creating YarnRPC for org.apache.hadoop.yarn.ipc.HadoopYarnProtoRPC 11/12/20 20:20:29 INFO mapred.ResourceMgrDelegate: Connecting to ResourceManager at dn5/192.168.3.204:50010 11/12/20 20:20:29 INFO ipc.HadoopYarnRPC: Creating a HadoopYarnProtoRpc proxy for protocol interface org.apache.hadoop.yarn.api.ClientRMProtocol 11/12/20 20:20:29 INFO mapred.ResourceMgrDelegate: Connected to ResourceManager at dn5/192.168.3.204:50010 11/12/20 20:20:29 WARN conf.Configuration: fs.default.name is deprecated.
