Subject how to print/refresh hadoop configs
Date Sat, 21 Nov 2009 22:20:54 GMT
Hi,
Environment :
     hadoop-0.20.1
     centos 5.0

On a live cluster, I want to do couple of actions

   1. Print the config properties for a datanode/tasktracker [any hadoop
      process] which it has in its jvm memory.
   2. Refresh the config properties of the datanode/tasktracker [any
      hadoop process] from the new/updated values in the
      hadoop/conf/*-site.xml files. Dont want to stop/start the
      processes if I dont have to.

Thanks,
Irfan
