What changes were proposed in this pull request?
When user calls anUDAF with the wrong number of arguments, Spark previously throws an AssertionError, which is not supposed to be a user-facing exception. This patch updates it to throw AnalysisException instead, so it is consistent with a regular UDF.
How was this patch tested?
Updated test case udaf.sql.
