Description

Query options automatically set by the Impala planner appear to not be reported in the runtime profile under the non-default query options.

Example query:

select * from functional.alltypes limit 1

The above query should trigger the single-node optimization and automatically set num_nodes=1, num_scanner_threads=1 and disable_codegen=true, but none of those changes are reported in the runtime profile under "Query Options (non default)".
