"process information unavailable", jps command in linux
<p>we use jps command to see which hadoop process is live, but since few days jps command is showing output like this.</p>

<pre><code>    [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
</code></pre>

<p>the actual ouput should be </p>

<pre><code>[root@slave ~]# jps
5039 Jps
2764 Application
2468 DataNode
2349 TaskTracker
</code></pre>

<p>is there any way which it will show me process information??</p>
