Subject [jira] [Updated] (SPARK-7706) Allow setting YARN_CONF_DIR from spark argument
Date Mon, 25 May 2015 07:21:18 GMT


Sean Owen updated SPARK-7706:
    Priority: Minor  (was: Major)

> Allow setting YARN_CONF_DIR from spark argument
> -----------------------------------------------
>                 Key: SPARK-7706
>                 URL:
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Submit
>    Affects Versions: 1.3.1
>            Reporter: Shaik Idris Ali
>            Priority: Minor
>              Labels: oozie, yarn
> Currently in SparkSubmitArguments.scala when master is set to "yarn" (yarn-cluster mode)
> Spark checks if YARN_CONF_DIR or HADOOP_CONF_DIR is set in EVN.
> However we should additionally allow passing YARN_CONF_DIR from command line argument
this is particularly handy when Spark is being launched from schedulers like OOZIE or FALCON.
> Reason being, oozie launcher App starts in one of the container assigned by Yarn RM and
we do not want to set YARN_CONF_DIR in ENV for all the nodes in cluster. Just passing the
argument like -yarnconfdir with conf dir (ex: /etc/hadoop/conf) should avoid setting the ENV
> This is blocking us to onboard spark from oozie or falcon. Thanks.
