Andras Salamon commented on OOZIE-2833:
---------------------------------------

I think OOZIE-3307 already solved this problem.

> when using uber mode the regex pattern used in the extractHeapSizeMB method 
> does not allow heap sizes specified in bytes.

> The extractHeapSizeMB method used here:
> https://github.com/apache/oozie/blob/9c0516608bdd0787b1fac3a69ccfe9d36cbb2d15/core/src/main/java/org/apache/oozie/action/hadoop/JavaActionExecutor.java#L401
> Uses the following pattern:
> -Xmx(([0-9]+)[mMgG])
> This requires that the -Xmx configuration option end in "m" or "g". However, 
> it is valid to configure this option in bytes without the "m" or "g" and this 
> will not be picked up.
