Change subject: IMPALA-4301: Fix IGNORE NULLS when subquery rewriting. ...................................................................... IMPALA-4301: Fix IGNORE NULLS when subquery rewriting. AnayticExpr.analyze() replaces the original FIRST/LAST_VALUE function with a FIRST/LAST_VALUE_IGNORE_NULLS function if the IGNORE NULLS clause is specified. The bug was that several places in AnalyticExpr.analyze() assumed and asserted that only the original FIRST/LAST_VALUE function could be encountered during analysis. However, with subquery rewriting the IGNORE NULLS version of the function may also be seen because the whole statement is re-analyzed after rewriting. The fix is to also accept the IGNORE NULLS version of the function.
