I'm having a hard time with the argument syntax in the catalog section of the manual. Help!

You should use the collectorSink. It is sufficient for most users and greatly simplifies configuration. The others are "low-level" and exposed for advanced users.

What is a good amount of time for collector rolling?

Plugins

I have a plugin that uses version xxx of Thrift and Flume is using version yyy.

Thrift versions have been wire-compatible from 0.5.0 to 0.6.0. Thus an application with a thrift 0.5.0 server should accept data from a thrift 0.6.0 client and vice-versa. I believe it has been wire compatible since 0.2.0 (NEEDS verification). The API generated code by the thrift compiler and the runtime libraries for java jars however, break compatibility. This will require a regeneration of thrift generated code. We suggest modifying the plugin as opposed to modifying flume or the target application.
