@vanzin Thanks. : )
I am testing using [OAP](https://github.com/Intel-bigdata/OAP) with
pre-built Spark on `LocalClusterMode`.
This is on travis and no SPARK_HOME is set.
The `mvn test` command will produce this error:
`23:49:56.997 ERROR org.apache.spark.deploy.worker.ExecutorRunner: Error
running executor
java.lang.IllegalStateException: Cannot find any build directories.
