Hi,

     nonroot 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

>From jps' man page:

DESCRIPTION
       The jps tool lists the instrumented HotSpot Java Virtual
Machines (JVMs) on the target system. The tool is limited to reporting
information on JVMs for which it  has
       the access permissions.

So normally it only shows you your own processes if you're not root.

By the way, this is not an HBase question, please stay on topic.
