Subject Re: Significance of PID files
Date Fri, 04 Jul 2014 05:33:48 GMT
Vikas,

"Its main use is to keep one process at a time...like one one datanode at a
any host" - Can you please elaborate in a more detail?

What is meant by one process at a time? At what level does a pid file come
into picture i.e. is it at a deamon level, job level, task level etc?

Thanks
Vijay
