Chris Howard commented on SPARK-11154:
--------------------------------------

Hi [~tgraves] - this overlaps to a point with 
[SPARK-3374|https://issues.apache.org/jira/browse/SPARK-3374] and 
[SPARK-4408|https://issues.apache.org/jira/browse/SPARK-4408]

I would agree with [~srowen] that 2.0 provides an opportunity for house keeping 
/ consolidation and there is scope to clean up the config / args for cluster 
and client modes.

I would prefer not to create new configs and would rather stick with the 
current naming and support k | m | g modifiers unless somebody has a strong 
view on what to rename the existing configs.

> spark.yarn.executor.memoryOverhead is currently specified in megabytes by 
> default, but it would be nice to allow users to specify the size as though it 
> were a typical -Xmx option to a JVM where you can have 'm' and 'g' appended 
> to the end to explicitly specify megabytes or gigabytes.
