Description

Impala query plan can be huge and complex.
It becomes hard to analyze this complex query plan, its execution summary, and the runtime filter interactions from the query profile.
We need tool to help visualize this query plan from plain text query profile.

One solution is to write a python script to parse the text profile into a GraphViz DOT format.
This DOT file can then be parsed into image using dot program or immediately visualize using program such as ZGRViewer.
