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?
