UDAF:FAILED: Execution Error

[Tamil A]

Hi Experts,

I have written an UDAF function and followed the below steps.

Step 1:
Export jar file

Step 2:
hive>ADD JAR /userdata/tamil/SumOfColumnTest/AvgOfColumn.jar;
(also tried with hive --auxpath
/userdata/tamil/SumOfColumnTest/AvgOfColumn.jar;

                      export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:
/userdata/tamil/SumOfColumnTest/AvgOfColumn.jar)
hive>list jar;
/userdata/tamil/SumOfColumnTest/AvgOfColumn.jar

Step 3;
hive>CREATE TEMPORARY FUNCTION avge AS 'com.hadoopbook.hive.UDAFExampleAvg';

but after this got the below error,
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.FunctionTask

is the above procedure i followed is same for UDF and UDAF or some other
changes are to be made for UDAF.


Please help me out,

Thanks & Regards,
Tamil
