> I am not aware of other breaking changes to 1.x files between 2.x and 3.x. but then I didn't follow file format work either, so this may just be my ignorance. > > While not a deal breaker, it would be nice if users could move tables and snapshots from 1.x clusters to 3.x clusters. We do not guarantee compatibility between 1.x and 3.x. This is intentional, to reduce the complexity for maintaining backward compatible code. So for releasing 3.0.0, we intentionally removed bunch of code related to 1.x. So I do not suggest we add something back, as users may still face other problems. For migrating tables and snapshots, I suggest we introduce tools in 2.x, to upgrade the data format to 2.x first, and then we are safe to upgrading to 3.x. If guys are OK with this, let me file an issue to introduce an 'upgrading tool'? Thanks. -- This is an automated message from the Apache Git Service.
