Why are you using 2.2? In general Cassandra, like most software, can lack
stability near the bleeding edge.

error: Error while rebuilding node: Stream failed

This is a relatively common issue with streaming in AWS.

What values did you try? What happened when you did this?

With data that small, you don't really need to use "rebuild," you could
just bootstrap the nodes one at a time. Of course bootstrap uses the same
streaming as rebuild so that doesn't really help, lol..

For issues like this, #cassandra on freenode IRC is often a good forum to
get help.
