Shreepadma Venugopalan updated HIVE-3241:
-----------------------------------------
Description:
GenericUDAFEvaluator has a member variable "Mode" which is protected. Accessing
mode in a GenericUDAF class raises IllegalAccessException when packaged as a
jar. This looks like a class loader issue because the error doesn't occur when
the jar is placed in HIVE_LIB directory. The fix for this issue is to provide
public getters for member variable mode in GenericUDAFEvaluator.
Steps to reproduce,
Copy the attached jar to a dir other than HIVE_LIB
On a hive shell,
add jar <path-to-jar>
create temporary function compute_stats as
'org.apache.hadoop.hive.ql.udf.generic.GenericUDAFComputeStats';
select compute_stats(some_col) from some_table;
