Github user samarthjain commented on the pull request: https://github.com/apache/phoenix/pull/153#issuecomment-208573524 @ankitsinghal - thanks for adding the upgrade util test. I have a question/suggestion: we should probably disallow users to execute create and use schema statements if the name space feature isn't enabled. I see that you are currently failing the upgrade if the name space feature isn't enabled which is good. To be consistent we should do the same for create and use schema statements. Another thing to think would be whether we should allow setting schema property on connection if name space feature is disabled. I lean towards not allowing it.
