Problem running Pig script with Jython

Hi,

I'm currently trying to run the following Jython script:

#!/usr/bin/python

from org.apache.pig.scripting import *

res = Pig.compile("""loaded1 = LOAD 'hbase://tfinger' USING
org.apache.pig.backend.hadoop.hbase.HBaseStorage('group_str:*', '-loadKey
true') AS (id:chararray, group:map[]);dump loaded1;""").bind().runSingle()
if res.isSuccessful():
  print 'SUCCESS'
else:
  print 'FAIL'

When I run it directly as a Pig script with the command "pig -x local
[RunPigScript.py]" it works fine. When I run it through Eclipse or directly
from the commandline with the Jython command I get the following error:


Traceback (most recent call last):
  File "RunPigScript.py", line 11, in <module>
    pig = Pig.compile("""
at org.apache.pig.scripting.Pig.getScriptContext(Pig.java:373)

java.io.IOException: java.io.IOException: Script context is not set

Any ideas on how to get around this issue? I'm running Pig 0.9.1 on local
mode.

Hi,

Sory for being repetitive but I just wanted to know if anyone had any idea
about how to get around this issue.
