Subject Re: Relation between threads and executor core
Date Wed, 26 Aug 2015 08:55:42 GMT
Hi Samya,

When submitting an application with spark-submit the cores per executor can
be set with --executor-cores, meaning you can run that many tasks per
executor concurrently. The page below has some more details on submitting
applications:

https://spark.apache.org/docs/latest/submitting-applications.html

thanks,

Jem
