Amareshwari Sri Ramadasu commented on HADOOP-2092:
--------------------------------------------------
Application is not generating any progress messages. I think we need a ping
mechanism from C++ process to Java task. I reproduced the problem by putting an
infinite loop in map method and killed Java map tasks when it is running. C++
processes does not die. But the application exits after trying 4 times.
> Pipes C++ task does not die even if the Java tasks die
