Design doc is attached, for comments/questions there's a google doc linked. > This issue covers phase-1 of abstraction work, which includes: > - infrastructure to support pluggable coordinated state managers > - abstraction of region opening/closing/splitting/merging operations > - abstraction of admin operation handlers like CreateTableHandler > - abstract ZKTable (reworked it to interface and implementation, allowing for new system tables-based impl to be developed) > - WAL splitting abstraction. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
