I'm fine with not waiting on the ext data source issue, but let's get Dimitris 
to OK this as well.

http://gerrit.cloudera.org:8080/#/c/2900/1/be/src/runtime/coordinator.cc
File be/src/runtime/coordinator.cc:

Line 519: scan nodes should use runtime filters
I'm confused by this... The frontend shouldn't be targeting filters at nodes 
that aren't capable of handling them, i.e. we shouldn't even be getting here 
once we fix the Frontend (which is a simple fix). When Dimitris makes that 
change, he should remove that TODO. 
Actually supporting runtime filters for HBase and Kudu scan nodes seems like a 
larger feature, not really tracked via a TODO.

What about saying
 
// TODO: Frontend should not target filters at unsupported scan nodes.
