Subject [jira] [Commented] (SPARK-5368) Support user configurable akka parameters.
Date Thu, 22 Jan 2015 16:42:35 GMT

    [ https://issues.apache.org/jira/browse/SPARK-5368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14287698#comment-14287698
] 

jay vyas commented on SPARK-5368:
---------------------------------

It could be a possibility that we can simply inject these into SparkConf, since the parameters
are acquired from {{conf.getAkkaConf}} , if so maybe this JIRA just is to add sufficient comments
and/or doc improvements to make it clear how to do so.

>                 URL: https://issues.apache.org/jira/browse/SPARK-5368
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 1.2.0
>            Reporter: jay vyas
>             Fix For: 1.2.2

>
> Spark sets up actors for akka with a set of variables which are defined in the {{AkkaUtils.scala}}
class.  
> A snippet:
> {noformat}
>  98       |akka.loggers = [""akka.event.slf4j.Slf4jLogger""]
>  99       |akka.stdout-loglevel = "ERROR"
> 100       |akka.jvm-exit-on-fatal-error = off
> 101       |akka.remote.require-cookie = "$requireCookie"
> 102       |akka.remote.secure-cookie = "$secureCookie"
> {noformat}
> We should allow users to pass in custom settings, for example, so that arbitrary akka
modifications can be used at runtime for security, performance, logging, and so on.
