Re: Which class or method is called first when i run a command in hadoop
Hi Nikhil,

Have a look inside the script file named hadoop inside hadoop bin folder.

for example:
C:\cygwin\home\hadoop-0.20.2\bin

sample code:
elif [ "$COMMAND" = "jar" ] ; then
  CLASS=org.apache.hadoop.util.RunJar
Cheers!
Manoj.
