Re: Pig not able to instantiate Python UDF

[Devi Kumarappan <kp...@att.net>]

I had the CLASSPATH set right.But the problem happen to be the jython version. 
When I installed jython 2.5.0, the problem got resolved.

correct the spelling of PIG_CALSSPATH to PIG_CLASSPATH
and its not CLASS_PATH .. just CLASSPATH

did you export them? like..

$ CLASSPATH=/path/to/jar_file1.jar:/path/to/jar_file2.jar:/path/to/jar_file3
.jar
$ PIG_CLASSPATH=
/path/to/jar_file1.jar:/path/to/jar_file2.jar:/path/to/jar_file3.jar
$
$ export CLASSPATH
$ export PIG_CLASSPATH
