I dug through more of the documentation on the new-fangled Storm project website and I didn't find docs speaking to upgrades of clusters.
We currently have a number of topologies built against 0.9.2-incubating and a number of clusters running 0.9.2-incubating and I'd like to start charting a course for upgrading to 0.9.3 across the board for a number of reasons. Is it possible to do a piece-meal supervisor/nimbus upgrade? In effect: * Bring new 0.9.3 supervisors online * Let 0.9.2 supervisors die * ?? nimbus ?? (I'm really not sure how to zero-downtime upgrade nimbus nodes) Or are you folks finding yourselves doing big-bang upgrades where you're either replacing or upgrading the whole cluster in place? I'm certain this isn't going to be a terrifically easy process but there's some Kafka fixes in 0.9.3 that will probably make it worth my time :) Cheers -R Tyler Croy
