Subject Re: Problems with Flume on windows with HTTP source
Date Fri, 21 Jun 2013 07:40:36 GMT
I am using Flume 1.3.1 and ran the example before sending.

I don't have access to a windows system at the moment so can't test.

This is output at my end on Flume Agent console

Flume dev's can comment further on this.
