Harsh J commented on OOZIE-2170:
--------------------------------
Overall the changes look good to me, +1.
Could you address the below minor thing during commit though?
{code}
+ if (sparkOptsSb.charAt(sparkOptsSb.length() - 1) == ' ') {
+ sparkOptsSb.setLength(sparkOptsSb.length() - 2);
+ }
{code}
We could instead use {{sparkOptsSb.toString().trim()}} when passing it forward
I think.

> If you use "yarn-cluster" for the Spark action's master, the Spark jobs don't
> show up in the Spark History Server or properly link to it from the Spark AM.
> The user needs to set this in their Spark action in the workflow.xml:
> {code:xml}
> <spark-opts>--conf spark.yarn.historyServer.address=http://SPH18088 --conf
> spark.eventLog.dir=hdfs://NN:8020/user/spark/applicationHistory --conf
> spark.eventLog.enabled=true</spark-opts>
> {code}
> It would be nice if Oozie did this automatically via some oozie-site.xml
> config(s). We could do something similar how the hadoop configs are setup
> where it will load a Spark .conf file from a directory based on the RM
> specified in the <job-tracker>.
> While we're at it, it might be good to document how to use Spark on YARN:
> # Include the spark-assembly jar with your workflow (this is unfortunately
> not published in maven)
> # Specify "yarn-cluster" as the master
> Also, the Spark example should delete the output dir in {{<prepare>}}
