Description

The external sort operator has a memory limit based on, among other things, the MAX_QUERY_MEMORY_PER_NODE constant. This constant is 2048 and it is assumed the caller will multiply by the appropriate factor to get the number of bytes.
The setting for external sort is not doing so.
It is better to fix the constant to specify the exact value in bytes.
