Java UDFs returning NULL difference between 2.7.0 and 2.8.0
Hi,
We just upgraded from CDH 5.9 (Impala 2.7.0) to latest (CDH 5.11.1 Impala 2.8.0)
We also have custom Java (Hive) UDFs used in Impala.
Before: select custom_udf_func(NULL) - returned NULL in the Java code - when executed by Impala it also returned NULL
NOW: select custom_udf_func(NULL) - returns NULL in the Java code - when executed by Impala it returns empty string ("")
Is that a bug in Impala (or maybe Hive) you are aware of?
Thanks,
Antoni
