Hi, I'm trying to run a multicluster storm setup. I've three machines, of which 1st one executes zookeeper, nimbus, and storm ui, while on 2nd and 3rd I'm running two supervisors.
When I look at the supervisor logs, I'm getting following error *b.s.m.n.StromClientErrorHandler [Info] Connection failed Netty-Client-<hostname of the other supervisor>:6700* *java.nio.channels.UnresolvedAddressException: null* * at sun.nio.ch.Net.checkAddress(Net.java:85) ~[na:1.7.0_17]* * at sun.nio.ch.SocketChannelImpl.connect(SocketChannelImpl.java:597) ~[na:1.7.0_17]* * at org.jboss.netty.channel.socket.nio.NioClientSocketPipelineSink.connect(NioClientSocketPipelineSink.java:106) ~[ne$* * at org.jboss.netty.channel.socket.nio.NioClientSocketPipelineSink.eventSunk(NioClientSocketPipelineSink.java:69) ~[n$* * at org.jboss.netty.handler.codec.oneone.OneToOneEncoder.handleDownstream(OneToOneEncoder.java:54) ~[netty-3.6.3.Fina$* * at org.jboss.netty.channel.Channels.connect(Channels.java:634) [netty-3.6.3.Final.jar:na]* * at org.jboss.netty.channel.AbstractChannel.connect(AbstractChannel.java:207) [netty-3.6.3.Final.jar:na]* * at org.jboss.netty.bootstrap.ClientBootstrap.connect(ClientBootstrap.java:229) [netty-3.6.3.Final.jar:na]* * at org.jboss.netty.bootstrap.ClientBootstrap.connect(ClientBootstrap.java:182) [netty-3.6.3.Final.jar:na]* * at backtype.storm.messaging.netty.Client.connect(Client.java:147) [storm-core-0.9.2-incubating.jar:0.9.2-incubating]* * at backtype.storm.messaging.netty.Client.access$000(Client.java:42) [storm-core-0.9.2-incubating.jar:0.9.2-incubatin$* * at backtype.storm.messaging.netty.Client$1.run(Client.java:104) [storm-core-0.9.2-incubating.jar:0.9.2-incubating]* * at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) [na:1.7.0_17]* * at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) [na:1.7.0_17]* * at java.util.concurrent.FutureTask.run(FutureTask.java:166) [na:1.7.0_17]* * at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:$* * at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:292) [n$* * at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [na:1.7.0_17]* * at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [na:1.7.0_17]* * at java.lang.Thread.run(Thread.java:722) [na:1.7.0_17]* I tried to telnet on the machine (telnet <ipaddress of other supervisor> 6700) with ipaddress it works fine, but not with the hostname of the other supervisor (telnet says unknown host). Any help is really appreciable. Many thanks, Ayush V.
