I am creating a new thread in forEachRdd function on dataframe using java . I want to know, will that thread execute as a task in worker node or it will execute as a normal java thread on the machine where i am doing spark submit. Please let me know the best way to perform the business actions on basis of data read through spark application.

Thanks in advance.
