Varun Vasudev commented on YARN-5621:
-------------------------------------

Thanks for the updated patch [~jianhe]. Couple of fixes for the latest patch -
1)
Can you look at the javac errors from Yetus? I'm not sure why your patch is 
triggerring them.

2)
{code}
+  pid_t child_pid = fork();
+  if (child_pid !=0) {
{code}

Can you differentiate between (child_pid > 0) - which means fork was successful 
and (child_pid < 0) - which means the fork failed?

Thanks!
