Hi Shyam, I find Eclipse especially useful for these kind of things. Follow the instructions at http://wiki.apache.org/hadoop/Hive/GettingStarted/EclipseSetup and run a unit test in debug mode and observe the stack.

Look at the run() method. That calls ParseDriver.parse() to get the AST. And them sem.analyze() to do semantic analysis, optimization and plan generation. Finally it goes through the Task list and runs the tasks according to the dependencies.

I can see Parser and Lexer generated by Antlr. Can someone please help me on the call sequence ? Where is the front level command processor that collects a query as a string and then calls parser? thanks, [email protected]
