> For some of the work I would like to do on HIVE-23149, it would be nice to
> visualize the output of the statement parser.
> I have created a tool that spits out the parser tree in DOT file format. This
> allows it to be visualized using a plethora of tools.
> To use it, compile the \{{hive-parser}} test JAR and run it. The application
> takes a single command line argument of a String. The String is the SQL
> statement to parse:
> {code:none}
> HqlParser "SELECT 1"
> {code}
> I have attached an example of the output that I generated for a {{SELECT 1}}
> statement:
>
>
> !select_1.png!
