> Issue Type: Improvement
> Components: Infrastructure
> Affects Versions: Impala 2.12.0, Impala 3.1.0
> Reporter: Zoram Thanga

> Introduce a Python GDB module, and a couple of commands that helps to find

> One hopes that folks will keep enhancing the module by adding new and useful
> GDB commands to aid debugging impalad core dumps.

> (gdb) find-query-ids
