Subject Re: Problems with Flume on windows with HTTP source
Date Fri, 21 Jun 2013 08:20:38 GMT
Hi Asish,

I think I found the problem - there must be something wrong with the
configuration and the source is not created. Unfortunately I can not figure
what.
Did you test it with my configuration?

Here is what I found in server log:
2013-06-21 11:01:24,433 (conf-file-poller-0) [DEBUG -
