I am new to HBASE, and while trying to install the same on Ubuntu system, I am facing some problem.

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.

what about Zookeeper ? is it running? – Arnon Rotem-Gal-Oz
Looking in the zookeeper logs would also be helpful. – phs
No zookeeper stopped running. – user3210024
No zookeeper stopped running. Detailed log is org.apache.zookeeper.server.PrepRequestProcessor: Got user-level KeeperException when processing sessionid:0x143ae8516780000 type:delete cxid:0xb zxid:0xba txntype:-1 reqpath:n/a Error Path:/hbase/backup-masters/localhost,60000,1390202397974 Error:KeeperErrorCode = NoNode for /hbase/backup-masters/localhost,60000,1390202397974 – user3210024

I recommend you to check the configurations used in hbase-site.xml. When not properly configured, zookeeper might stop running and you will get such strange exceptions.
