Minor Description
This ticket was created based on the following comment from mberman in ACCUMULO-1009. I copied the comment in case the link comment stops working.
Multiple ZooKeeperInstances in the same java process with different SSL config (is this possible? It looks like you included ssl options in the Key in ThriftTransportPool?) This could happen if a single process connected to multiple Accumulo instances
Generally this should be fine. The cached transports are keyed on (location, timeout, sslEnabled), so if you're connecting to multiple instances from the same process, they should have different locations anyway, so the different SSL settings will be segregated. One potential area for concern is that I'm only using the sslEnabled flag, not the full set of SSL parameters, so if you have connected successfully with some cert, and then in the same process you try to connect with a different cert, you could get a cached, connected transport, even though you might not otherwise trust the remote server (or you might have an invalid client cert, if that's turned on). It seemed to me like this risk was pretty minimal, since you're already in the same process, but if others think it's too big a risk, it would be easy to add all the SSL params to the key.
