Each hostname resolve to IP correctly . Each machine is able to ping each other as well as passwordless SSH is also working fine. I wanted to start regionserver on all 3 machines so I updated conf/regionserver file with hostname of different machine. Firewall is off in each machine. Cluster Config: Master Machine : master Slave Machine : slave slave2 When Hbase master try to start daemons on slave2 machine, it shows up error and then shuts down : Error : 2011-09-21 16:35:57,444 DEBUG org.apache.hadoop.hbase.master.ServerManager: New connection to slave2,60020,1316600151864 2011-09-21 16:35:57,445 INFO org.apache.hadoop.ipc.HbaseRPC: Server at /10.33.100.74:60020 could not be reached after 1 tries, giving up. 2011-09-21 16:35:57,445 WARN org.apache.hadoop.hbase.master.AssignmentManager: Failed assignment of testreplication,,1316167978748.34a750440de259a5c5c919ab9930f874. to serverName=slave2,60020,1316600151864, load=(requests=0, regions=0, usedHeap=22, maxHeap=995), trying to assign elsewhere instead; retry=0 org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed setting up proxy interface org.apache.hadoop.hbase.ipc.HRegionInterface to /10.33.100.74:60020 after attempts=1 at org.apache.hadoop.hbase.ipc.HBaseRPC.waitForProxy(HBaseRPC.java:355) at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.getHRegionConnection(HConnectionManager.java:957) at org.apache.hadoop.hbase.master.ServerManager.getServerConnection(ServerManager.java:618) at org.apache.hadoop.hbase.master.ServerManager.sendRegionOpen(ServerManager.java:553) at org.apache.hadoop.hbase.master.AssignmentManager.assign(AssignmentManager.java:931) at org.apache.hadoop.hbase.master.AssignmentManager.assign(AssignmentManager.java:746) at org.apache.hadoop.hbase.master.AssignmentManager.assign(AssignmentManager.java:726) at org.apache.hadoop.hbase.master.handler.ClosedRegionHandler.process(ClosedRegionHandler.java:92) at org.apache.hadoop.hbase.executor.EventHandler.run(EventHandler.java:156) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: java.net.ConnectException: Connection refused >From the logs it shows that its proxy issue , but since the slave2 is in same >network as with slave, master Im not sure why it is happening.
