Subject Re: How to track batch jobs in spark ?
Date Thu, 06 Dec 2018 22:13:47 GMT
Hi Kant,

why would you want to kill a batch job at all, it leads to half written
data in to the disk, and sometimes other issues. The general practice is to
have exception handling code.

In case you are running into scenarios where the code is just consuming too
much resources and you are running the spark job locally, I would prefer
killing the entire spark application from command line using unix kill
command or stop-all.sh.

Otherwise, as Jayesh mentioned killing from the application also makes
sense.

Regards,
Gourav
