Heji Kim commented on SPARK-8939:
---------------------------------
I was trying to upgrade to 1.5 today and could not submit drivers due to this
error. Please note that I get this error even when I specify the num-executors.
If I use either --num-executors 6 or --conf spark.executor.instances=6
I will get the following error message:
"Unknown/unsupported param List(--num-executors, 6)"
This is preventing us from upgrading to 1.5 unless there is another workaround.
