How to apply the ganglia patch to my distro?

Hi,
    What are the changes I need to make to run ganglia 3.1.7 on hadoop
0.20.2? I have used GangliaContext31, but I think I'll also need to apply
the 4675 patch <https://issues.apache.org/jira/browse/HADOOP-4675>. How do I
apply the patch to my distribution? And which of the patched works best?

thanks,
hari

Hi Brian,

           Thank you for the response :)I have used GangliaContext31 in the
properties file and it did not throw any exception when I start up the
cluster. Does this mean that my version is patched? Because I am not able to
see any new metrics in ganglia. What are the additional metrics that ganglia
shows for hadoop?

Hi Hari,

If you have GangliaContext31, then someone has already applied HADOOP-4675.  Or are you saying you put it into the hadoop-metrics.properties and it tossed an exception?

You can read how to apply a patch and build Hadoop here: http://wiki.apache.org/hadoop/HowToContribute

If you look at the JIRA, you probably want to apply the latest patch if you're using the latest Hadoop code; if you're using an older version than the trunk (like 0.20), you might have to read through and figure out which one corresponds to your release.
