Hey Dan,

You say that it seems like Flume has already processed the log... why do
you think that?

When you listed the directory contents I don't see the original or the
COMPLETED version of the file that Flume is complaining about:

/clickstream.log-2012-11-17-1353163623

doesn't appear in the

/mnt/flume/clickstream/

directory listing anywhere.
