Hi,

     not  root user can not find all the hadoop process.

     1. root use find all the process, below:
[root@hadoop1 ~]# jps
17452 SecondaryNameNode
18266 Main
7759 Jps
32095 QuorumPeerMain
17108 JobTracker
16955 TaskTracker
17566 HMaster
17177 NameNode
17765 HRegionServer
19424 ThriftServer
17303 DataNode

   2.  but nonroot user only find some, below:


-bash-4.1$ jps
17452 SecondaryNameNode
7736 Jps
17177 NameNode
17303 DataNode

3. maybe .bash_profiel problem?

Thanks!
