Subject sleep() in script doesn't work when called by exec Source
Date Mon, 19 Aug 2013 02:29:48 GMT
Hi,

I am testing with apache-flume-1.4.0-bin.
I made a naive python script for exec source to do throttling by calling sleep() function.
But the sleep() doesn't work when called by exec source.
Any ideas about this or do you have some simply solution for throttling instead of a custom
source?

Flume config:


agent.sources = src1
agent.sources.src1.type = exec
agent.sources.src1.command = read-file-throttle.py

read-file-throttle.py:


#!/usr/bin/python

import time

count=0
pre_time=time.time()
with open("apache.log") as infile:
    for line in infile:
        line = line.strip()
        print line
        count += 1
        if count % 50000 == 0:
            now_time = time.time()
            diff = now_time - pre_time
            if diff < 10:
                #print "sleeping %s seconds ..." % (diff)
                time.sleep(diff)
                pre_time = now_time


Thank you very much.

Best Regards,
Yongkun Wang
