--------------------------------------
+1 from me,
That would have been really handy today - we could have done some K-mean
clustering with SQL -

Now we have to do it with python :)
> Support recursive WITH clause
> -----------------------------

> Project: IMPALA
> Issue Type: New Feature
> Components: Backend, Frontend
> Affects Versions: Impala 1.2.1
> Environment: All
> Reporter: Manoj Samel
> Priority: Major
> Labels: sql-language

> Impala SQL does not support the recursive "WITH" clause.
> Recursive WITH clauses are very useful in writing modular parts of complex
> queries that does not makes the main query too complex.
> Support for reursive WITH clause should be added.
