Merge pull request #259 from pwendell/scala-2.10
Migration to Scala 2.10
== Below description was written by Prashant Sharma ==
This PR migrates spark to scala 2.10.
Summary of changes apart from scala 2.10 migration:
(has no implications for user.)
1. Migrated Akka to 2.2.3.
Does not use remote death watch for it has a bug, where it tries to send
message to dead node infinitely.
Uses an indestructible actorsystem which tolerates errors only on executors.
(Might be useful for user.)
4. New configuration settings introduced:
System.getProperty("spark.akka.heartbeat.pauses", "600")
System.getProperty("spark.akka.failure-detector.threshold", "300.0")
System.getProperty("spark.akka.heartbeat.interval", "1000")
Defaults for these are fairly large to only disable Failure detector that comes
with akka. The reason for doing so is we have our own failure detector like
mechanism in place and then this is just an overhead on top of that + it leads
to a lot of false positives. But with these properties it is possible to enable
them. A good use case for enabling it could be when someone wants spark to be
sensitive (in a controllable manner ofc.) to GC pauses/Network lags and quickly
evict executors that experienced it. More information is included in
configuration.md
Once we have the SPARK-544 merged, I had like to deprecate atleast these akka
properties and may be others too.
This PR is duplicate of #221(where all the discussion happened.) for that one
pointed to master this one points to scala-2.10 branch.
