---------------------------------------

             Summary: Reduce jython function initiation during compilation
                 Key: PIG-4913
                 URL: https://issues.apache.org/jira/browse/PIG-4913
             Project: Pig
          Issue Type: Improvement
            Reporter: Rohini Palaniswamy


While investigating PIG-4908, saw that ScriptEngine.getScriptAsStream was invoked way too many times during compilation phase for a simple script.

{code:title=sleep.py}
#!/usr/bin/python

import time;

@outputSchema("sltime:int")
def sleep(num):
    if num == 1:
        print "Sleeping for %d minutes" % num;
        time.sleep(num * 60);
    return num;
{code}
{code:title=sleep.pig}
register 'sleep.py' using jython;

A = LOAD '/tmp/sleepdata' as (f1:int);
B = FOREACH A generate $0, sleep($0);
STORE B into '/tmp/tezout';
{code}
