> Taking IMPALA-6191 one step further it would be great to provide a way to obtain stack traces for all threads that are currently executing a particular query / fragment / instance.
> To achieve this we can re-use Kudu's {{DumpThreadStack()}}. Another option would be to re-use minidumps and filter them with some additional tool / script.
