Change subject: IMPALA-12744: Support for regr_count() aggregate/analytic function ...................................................................... IMPALA-12744: Support for regr_count() aggregate/analytic function The regr_count() function can be used both as an aggregate and an analytic function and is commonly used in regression analysis. regr_count(y, x) returns an integer that is the number of non-null number pairs. It indicates how many observations are included in the analysis. Testing: The functions are extensively tested and cross-checked with Hive. The tests can be found in aggregation.test.
