Subject RE: flume windows node - 404 on localhost
Date Tue, 24 Jan 2012 19:58:55 GMT

I had .9.4.  Now changing it to .9.3, brings up the agent page. I'll have to try the transmitting
data part.  I have no luck so far.

Looks like only 0.9.4 is not working.  In the hadoop cluster we have CDH3u2 which comes with
Flume 0.9.4

Is it okay to have different versions on master and nodes?

What version are you using?

what says the log file? 
What version you installed?

did you commented out the flume-conf.xml and comment out the master-stuff. (pre NG).

You can get this by configuring your flow with reliable channels (JDBC).
