Comment savoir quelle est la raison de l'exception ClosedChannelException avec spark-shell en mode client YARN?

J'ai essayé d'exécuter spark-Shell en mode YARN client, mais j'ai de nombreuses erreurs ClosedChannelException J'utilise spark 2.0.0 build pour Hadoop 2.6.

Voici les exceptions:

$ spark-2.0.0-bin-hadoop2.6/bin/spark-Shell --master yarn --deploy-mode client

To adjust logging level use sc.setLogLevel(newLevel).

Une association avec un groupe de fils peut être perdue à cause du problème d'allocation de mémoire excessive de Java 8: https://issues.Apache.org/jira/browse/YARN-4714

Vous pouvez forcer YARN à ignorer cela en définissant les propriétés suivantes dans yarn-site.xml

<property>
    <name>yarn.nodemanager.pmem-check-enabled</name>
    <value>false</value>
</property>

<property>
    <name>yarn.nodemanager.vmem-check-enabled</name>
    <value>false</value>
</property>

Grâce à simplejack, Référence de Exemple Spark Pi en mode cluster avec Fil: Association perdue

Personnellement, j'ai résolu ceci en augmentant yarn.nodemanager.vmem-pmem-ratio comme suggéré dans le billet Jira by Akira Ajisaka :

<property>
    <name>yarn.nodemanager.vmem-pmem-ratio</name>
    <value>5</value>
</property>

J'ai construit une autre réponse qui dépend si vous utilisez le mode client spark ou cluster. 

  • En mode cluster, cela a échoué lorsque j'ai spécifié que Driver Memory --driver-memory était 512m. (Le paramètre par défaut demandait 2 Go de ressources am (Cela consiste en mémoire du pilote + surcharge demandée pour le maître d’application) ce qui était suffisant)
  • En mode client, le paramètre qui importait était spark.yarn.am.memory car, par défaut, il ne demandait que 1024 m pour le MA, ce qui est trop peu, car Java 8 nécessite beaucoup de mémoire virtuelle. > 1024m semblaient fonctionner.

La réponse est décrite ici
