-Re: Unable to activate flume-ng-cassandra-sink

The reason I don't recommend using it is that I didn't know it existed :P
That seems like a great place to put it. I've done quite a bit of
customization, so for me it's easier to just point Flume to the ./target
directory of my java projects. But the plugins.d seems like a great place
for third-party libraries.
Glad I could help!
