To reply, visit: https://reviews.apache.org/r/1757/ --- Review request for hive and John Sichi. Summary --- By default patterntype is complex so it is expecting Pattern object but in this scenario pattern object is null so it is throwing nullpointer exception. Default patterntype can be NONE and in parseSimplePattern() it will be assigned with right type. This addresses bug HIVE-2402. https://issues.apache.org/jira/browse/HIVE-2402 Diffs - trunk/ql/src/java/org/apache/hadoop/hive/ql/udf/UDFLike.java 1165244 trunk/ql/src/test/queries/clientpositive/udf_like.q 1165244 trunk/ql/src/test/results/clientpositive/udf_like.q.out 1165244 Diff: https://reviews.apache.org/r/1757/diff Testing --- Added unit testcase.
