> Cannot implement nor use custom StandaloneRecoveryModeFactory implementations
> -----------------------------------------------------------------------------
>
>                 Key: SPARK-7436
>                 URL: https://issues.apache.org/jira/browse/SPARK-7436
>             Project: Spark
>          Issue Type: Bug
>    Affects Versions: 1.3.1
>            Reporter: Jacek Lewandowski
>            Assignee: Apache Spark
>
> At least, this code fragment is buggy ({{Master.scala}}):
> {code}
>       case "CUSTOM" =>
>         val clazz = Class.forName(conf.get("spark.deploy.recoveryMode.factory"))
>         val factory = clazz.getConstructor(conf.getClass, Serialization.getClass)
>           .newInstance(conf, SerializationExtension(context.system))
>           .asInstanceOf[StandaloneRecoveryModeFactory]
>         (factory.createPersistenceEngine(), factory.createLeaderElectionAgent(this))
> {code}
> Because here: {{val factory = clazz.getConstructor(conf.getClass, Serialization.getClass)}} it tries to find the constructor which accepts {{org.apache.spark.SparkConf}} and class of companion object of {{akka.serialization.Serialization}} and then it tries to instantiate {{newInstance(conf, SerializationExtension(context.system))}} with instance of {{SparkConf}} and instance of {{Serialization}} class - not the companion objects.
