Nathan Skone commented on OOZIE-2391:
-------------------------------------
Robert,
You can indeed specify multiple --conf entries, but only the last one seems to
be effective. For example, I used this spark-opts:
<spark-opts>--conf spark.driver.extraJavaOptions=-Denv=qa --conf
spark.driver.extraJavaOptions=-XX:MaxPermSize=256M</spark-opts>
In this case, both arguments were passed to Spark as follows:
--conf
spark.driver.extraJavaOptions=-Denv=qa
--conf
spark.driver.extraJavaOptions=-XX:MaxPermSize=256M
However, Spark only used the second spark.driver.extraJavaOptions, ignoring the
first.
Thanks,
Nathan

> When providing spark-opts in workflow.xml for oozie, the "--conf" property
> values is not parsed properly.
> Example sparkopts
> <spark-opts>--conf
> spark.executor.extraJavaOptions=-Dconfig.url=hdfs:///my.conf
> -Dmy.env=${env}</spark-opts>
> In this case the value for property "spark.executor.extraJavaOptions" is
> "-Dconfig.url=hdfs:///my.conf -Dmy.env=${env}", but in the oozie code here
> https://github.com/apache/oozie/blob/38e33811bc3f9d3b1a1a024dcab6af760734b696/sharelib/spark/src/main/java/org/apache/oozie/action/hadoop/SparkMain.java#L110
> the string is just split by space, which make the "-Dmy.env=${env}" a
> separate argument to spark and spark fails job as that argument is not valid.
> This doesn't work with enclosing the whole value in quotes too.
> Error from stderr:
> Error: Unrecognized option '-Dmy.env=development"'.
> Run with --help for usage help or --verbose for debug output
> Intercepting System.exit(1)
> Failing Oozie Launcher, Main class
> [org.apache.oozie.action.hadoop.SparkMain], exit code [1]
