Parth Chandra reopened DRILL-1848:
----------------------------------
External sort also uses a deprecated method to allocate memory for vectors,
which has not been updated for complex types. The additional patch addresses
that.
> Query involving external sort runs out of memory

>
> 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.
