## What changes were proposed in this pull request? Enabled SparkR with Mesos client mode and cluster mode. Just a few changes were required to get this working on Mesos: (1) removed the SparkR on Mesos error checks and (2) do not require "--class" to be specified for R apps. The logic to check spark.mesos.executor.home was already in there. sun-rui ## How was this patch tested? 1. SparkSubmitSuite 2. On local mesos cluster (on laptop): ran SparkR shell, spark-submit client mode, and spark-submit cluster mode, with the "examples/src/main/R/dataframe.R" example application. 3. On multi-node mesos cluster: ran SparkR shell, spark-submit client mode, and spark-submit cluster mode, with the "examples/src/main/R/dataframe.R" example application. I tested with the following --conf values set: spark.mesos.executor.docker.image and spark.mesos.executor.home This contribution is my original work and I license the work to the project under the project's open source license.
