"process information unavailable", jps command in linux

we use jps command to see which hadoop process is live, but since few days jps command is showing output like this.

    [root@master ~]# jps
    3814 -- process information unavailable
    2266 -- process information unavailable
    6197 -- process information unavailable
    7092 Jps
    6415 -- process information unavailable
    6027 -- process information unavailable

the actual ouput should be 

[root@slave ~]# jps
5039 Jps
2764 Application
2468 DataNode
2349 TaskTracker

is there any way which it will show me process information??

Just remove hsperfdata_ folder from your /tmp folder and run jps again.
