Subject what time task is marked with SUCCESSED
Date Thu, 30 Jul 2009 08:19:12 GMT
Hi all,

I would like to know who marks task running status with SUCCESSED when
a task is finished.

I have traced the hadoop source codes, but I lost the trace when
JvmManager takes charge of
a task running. I can not find (also, don't know) who (tasktracker or
jobtracker) checks the running
result of a finished task and how to know a task is finished
successfully or in fail, so that marks
the task status.

In which files, I can find the codes which are relative with above
functionalities ?


Thanks in advance,

Ian
