Marcelo Vanzin commented on SPARK-5861:
---------------------------------------
bq. In ClientArguments.scala, cluster mode is detected by the presence of
-class, but it's perfectly possible set -class with yarn-client mode.
It may be possible, but I think the code doesn't do it. Since {{Client}} as a
public API is deprecated, that's probably a minor issue.
> [yarn-client mode] Application master should not use memory =
