Hi, I just wrote an application that intends to submit its actions(jobs) via independent threads keeping in view of the point: "Second, within each Spark application, multiple “jobs” (Spark actions) may be running concurrently if they were submitted by different threads", mentioned in: https://spark.apache.org/docs/0.9.0/job-scheduling.html
val a = sc.textFile("hdfs:\.....") val b =a.sometransformations Thread1 = { /* An action on RDD b */ } Thread2 = { /* An action on RDD b */ } and so on. Basically, different actions are performed on same RDD. Now, I just want to know if writing code like this with threads makes any difference in execution when there are no threads written in the code ( It means all actions are submitted via one thread, I guess). Before that, is this a way to submits actions via multiple threads?
