Subject [jira] [Updated] (HIVE-3241) GenericUDAF when packaged as a JAR raises IllegalAccessException unless the JAR is placed in lib dir
Date Fri, 06 Jul 2012 22:32:40 GMT

     [ https://issues.apache.org/jira/browse/HIVE-3241?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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;


  was:GenericUDAFEvaluator has a member variable "Mode" which is protected. Accessing mode
