    Description

      The yarn alpha version of calculateAMMemory takes into account the minimum resource capability and also subtracts out YarnAllocationHandler.MEMORY_OVERHEAD.

      The yarn stable version just sets the -Xmx to whatever is passed in by the user.

      The 2 of these should be the same.

      Personally I also think its weird how spark currently takes whatever user passes in for memory and adds YarnAllocationHandler.MEMORY_OVERHEAD to request to RM. This can be confusing to users. We should revisit all of this and commonize the stable/alpha code where possible.
