spark.akka.timeout |
- 20 |
+ 60 |
Communication timeout between Spark nodes, in seconds.
|
+
+ spark.akka.pauses |
+ 60 |
+
+ Acceptable heart beat pause in seconds for akka, tune this if you expect GC pauses or network delays (reconnections) etc.
+ |
+
+
+ spark.akka.failure-detector.threshold |
+ 12.0 |
+
+ Tuning this is not recommended unless you are sure what you are doing. This maps to akka's `akka.remote.transport-failure-detector.threshold`. Usually having a larger value of `spark.akka.pauses` should suffice.
+ |
+
+
+ spark.akka.heartbeat.interval |
+ 5 |
+
+ A larger interval value in seconds reduces network overhead and a smaller value might be more informative for akka's failure detector. Tune this in combination of `spark.akka.pauses` and `spark.akka.failure-detector.threshold` if you need to.
