Below is the error log from Zookeeper log file

2014-01-18 06:10:51,392 WARN org.apache.zookeeper.server.NIOServerCnxn: caught end of stream exception EndOfStreamException: Unable to read additional data from client sessionid 0x143a5b052980000, likely client has closed socket at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:220) at org.apache.zookeeper.server.NIOServerCnxnFactory.run(NIOServerCnxnFactory.java:208) at java.lang.Thread.run(Thread.java:744) 2014-01-18 06:10:51,394 INFO org.apache.zookeeper.server.NIOServerCnxn: Closed socket connection for client /127.0.0.1:56671 which had sessionid 0x143a5b052980000

Below is error log from master log:

2014-01-18 06:10:51,381 INFO org.apache.zookeeper.ZooKeeper: Session: 0x143a5b052980000 closed 2014-01-18 06:10:51,381 INFO org.apache.hadoop.hbase.master.HMaster: HMaster main thread exiting 2014-01-18 06:10:51,381 ERROR org.apache.hadoop.hbase.master.HMasterCommandLine: Failed to start master java.lang.RuntimeException: HMaster Aborted at org.apache.hadoop.hbase.master.HMasterCommandLine.startMaster(HMasterCommandLine.java:160) at org.apache.hadoop.hbase.master.HMasterCommandLine.run(HMasterCommandLine.java:104) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.hadoop.hbase.util.ServerCommandLine.doMain(ServerCommandLine.java:76) at org.apache.hadoop.hbase.master.HMaster.main(HMaster.java:2120)

Please note, I am able to start Hbase successfully. I mean after starting Hbase, I am able to see Hmaster running using jps command. But as soon as I try to go to Hbase shell, this issue arises and then by executing jps command, I don’t find Hmaster in list.

Please help me in this issue, as I tried to solve it by myself from last for days, but no luck. Please help

You will need a dynamic DNS acount. http://www.dyndns.org I have included a link with step by step instructions.

Robert, I think I might have a solution for your DNS problem.
Ubuntu, by default, adds a line ‘127.0.1.1 somehostname’ to your /etc/hosts.
Remove this line, and your problems might just be fixed.

I’m still having a bit of trouble understanding what the right way is to build from source and then use though. Should I really be doing ant package and then use the package?

Its even worse when I try to deploy it to Amazon EC2 where it resolves the DNS to the NAT’d local address even if you specify the DNS FQDN of the public ip address!

When I figure it out, I’ll publish it here and make a comment. I think you get an automatic notification…

It does definitely do full DNS look up as I resorted to adding a sub-domain on our public DNS server for it. It returns a private IP so it will still only be available internally.
