Hello I have a 3-node cluster where I have installed hadoop 2.7.3. I have updated core-site.xml, mapred-site.xml, slaves, hdfs-site.xml, yarn-site.xml, hadoop-env.sh files with basic settings on all 3 nodes.
When I execute start-dfs.sh on the master node, the namenode does not start. The logs contain the following error - 2017-04-27 14:17:57,166 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: Failed to start namenode. java.net.BindException: Problem binding to [master:51150] java.net.BindException: Cannot assign requested address; For more details see: http://wiki.apache.org/hadoop/BindException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.apache.hadoop.net.NetUtils.wrapWithMessage(NetUtils.java:792) at org.apache.hadoop.net.NetUtils.wrapException(NetUtils.java:721) at org.apache.hadoop.ipc.Server.bind(Server.java:425) at org.apache.hadoop.ipc.Server$Listener.<init>(Server.java:574) at org.apache.hadoop.ipc.Server.<init>(Server.java:2215) at org.apache.hadoop.ipc.RPC$Server.<init>(RPC.java:951) at org.apache.hadoop.ipc.ProtobufRpcEngine$Server.<init>(ProtobufRpcEngine.java:534) at org.apache.hadoop.ipc.ProtobufRpcEngine.getServer(ProtobufRpcEngine.java:509) at org.apache.hadoop.ipc.RPC$Builder.build(RPC.java:796) at org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.<init>(NameNodeRpcServer.java:345) at org.apache.hadoop.hdfs.server.namenode.NameNode.createRpcServer(NameNode.java:674) at org.apache.hadoop.hdfs.server.namenode.NameNode.initialize(NameNode.java:647) at org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:812) at org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:796) at org.apache.hadoop.hdfs.server.namenode.NameNode.createNameNode(NameNode.java:1493) at org.apache.hadoop.hdfs.server.namenode.NameNode.main(NameNode.java:1559) Caused by: java.net.BindException: Cannot assign requested address at sun.nio.ch.Net.bind0(Native Method) at sun.nio.ch.Net.bind(Net.java:433) at sun.nio.ch.Net.bind(Net.java:425) 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:408) ... 13 more 2017-04-27 14:17:57,171 INFO org.apache.hadoop.util.ExitUtil: Exiting with status 1 2017-04-27 14:17:57,176 INFO org.apache.hadoop.hdfs.server.namenode.NameNode: SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down NameNode at master/1.1.1.1 ************************************************************/ I have changed the port number multiple times, every time I get the same error. How do I get past this? Thanks Bhushan Pathak
