---------------------------------------
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}
