Hi Shashwat,
I want to tell you about my configurations:
I am using 4 nodesOne "Master": Namenode, SecondaryNamenode, Job Tracker,
Zookeeper, HMasterThree "Slaves": datanodes, tasktrackers, regionservers
In both master and slaves, all the hadoop daemons are working well, but as for
the hbase master service it is not working..
As for region server here is the error:12/05/12 14:42:13 INFO
