hbase master log http://pastebin.com/TUvx4BgX ?

Answer 1

Your hbase master is not starting properly,that is why it is unable to connect to 60000 port.Check the following in your hadoop and hbase conf.

1. In the hbase/conf/hbase-site.xml.check the value of the hbase.master property.it should be 60000.
2. check if the port in the hbase conf is properly configured with the hadoop port.
3. check if the zookeeper conf is having the same port of hbase master.

Also do netstat and check whether hadoop and hbase port are available.

If you can attach the conf file,i would able to give you more details
