MJ may wanna do another pass.
File be/src/runtime/runtime-state.h:

PS1, Line 294:   /// Returns a non-OK status if query execution should stop (e.g., the query
             :   /// cancelled or a mem limit was exceeded). Exec nodes should check this
periodically so
             :   /// execution doesn't continue if the query terminates abnormally. This should
not be
             :   /// called after ReleaseResources().
             :   Status CheckQueryState();
> How about we rename them to be less vague. Maybe something like:
I wonder if most of the remaining callers can be converted to CheckQueryStatus() given that
we do mostly use TryAllocate() instead of Allocate(). Most of the remaining callers are DataSinks.
May be if we fix hdfs-table-writer and friends to use TryAllocate(), things will be easier
