call trace help
Hi all,
I am interested to see the each and every call trace if i issue a command
for ex : $bin/hadoop dfs -copyFromLocal /tmp/file.txt /user/hadoop/file.txt
or while running a M/R job .....
Is there any command to sprinkle the logs at the begin of each and every
function and build the source ....
may i know how to go about doing this ?

I have never met a man so ignorant that i couldn't learn something from him

Sample: java -Xdebug

You can find more example on the internet.

Run the daemons in debug mode and attach eclipse as a remote debugger to
