When hive.cache.expr.evaluation is set to true (which is the default) a UDF can give incorrect results if it is nested in another UDF or a Hive function. This bug affects releases 0.12.0, 0.13.0, and 0.13.1. Release 0.14.0 will fix the bug (HIVE-7314). The problem relates to the UDF's implementation of the getDisplayString method, as discussed in the Hive user mailing list. |
