> 0.99.0 comes with dist log replay by default (HBASE-10888). However, reading
> the code and discussing this with Jeffrey, we realized that the dist log
> replay code is not compatible with rolling upgrades from 0.98.0 and 1.0.0.
> The issue is that, the region server looks at it own configuration to decide
> whether the region should be opened in replay mode or not. The open region
> RPC does not contain that info. So if dist log replay is enabled on master,
> the master will assign the region and schedule replay tasks. If the region is
> opened in a RS that does not have this conf enabled, then it will happily
> open the region in normal mode (not replay mode) causing possible (transient)
> data loss.
