Re: Install hbase on Ubuntu 11.10

Hi Debarshi,

You can use JPS to list the java deamons running on your different machines.

You should see at least those one:
3420 QuorumPeerMain
2564 TaskTracker
2252 NameNode
2456 DataNode
2360 JobTracker
2703 HMaster
2815 HRegionServer

The number is  the process number so will change each time you start
the application. And all those process can be on different machines,
not necessary the same one.

If you have all those process running, then you should take a look at
the logs files.
