And we do not want to inconvenience the user by requiring a two step rolling upgrade. > Thus I think we should disable dist log replay for 1.0, and re-enable it again for 1.1 (if rolling upgrade from 0.98 is not supported). > ie. undo: HBASE-10888 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
