Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/5809/1/docs/topics/impala_known_issues.xml File docs/topics/impala_known_issues.xml: PS1, Line 810: for example when Impala applied the single-node : optimization for small queries. John, sorry for the confusion. After the fix of IMPALA-4432, IR UDF will still work with single-node optimization. The cases with behavioral change are when the user explicitly sets disable_codegen=true in the query options and attempts either of the followings: - running IR UDF will get the following error message: https://github.com/apache/incubator-impala/blob/master/be/src/exprs/scalar-fn-call.cc#L127 - running a built-in or native UDF with more than 20 arguments will result in the following error message: https://github.com/apache/incubator-impala/blob/master/be/src/exprs/scalar-fn-call.cc#L137 -- To view, visit http://gerrit.cloudera.org:8080/5809 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: Ibeed92e8f6603b858622b1d397d1f5cad810f4cf Gerrit-PatchSet: 1 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: John Russell <jruss...@cloudera.com> Gerrit-Reviewer: Michael Brown <mi...@cloudera.com> Gerrit-Reviewer: Michael Ho Gerrit-Reviewer: Michael Ho <k...@cloudera.com> Gerrit-Reviewer: Sailesh Mukil <sail...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-HasComments: Yes
