Subject [jira] Created: (HADOOP-4959) System metrics does not output correctly for Redhat 5.1.
Date Tue, 30 Dec 2008 22:06:44 GMT
System metrics does not output correctly for Redhat 5.1.
--------------------------------------------------------

                 Key: HADOOP-4959
                 URL: https://issues.apache.org/jira/browse/HADOOP-4959
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/chukwa
         Environment: Redhat EL 5.1, Java 6
            Reporter: Eric Yang
            Assignee: Eric Yang


Top output is different between Redhat 4.5 and Redhat 5.1.  The demux parser needs to be updated
to parse information correctly.

>From Redhat EL 4.5:

Notice in 5.1, there is a % for st.  

The parser needs to be improved.
