As you guys may already be familiar, Vladimir, Ted, Jerry and others have been developing the backup / restore functionality in a series of issues committed in the separate branch HBASE-7912[1].
Backup / Restore functionality is tracked as a 4-phase project, and the first two phases are complete and useable. We are now working on Phase 3 items, which are mostly improvements. We think that the current code in the branch containing all Phase 1 and Phase 2 items, and some Phase 3 items is useable on it's own, and we do not have to wait for all the subtickets to be finished to make it completely useable (as follow up tickets are mostly improvements or optimizations). The improvements in the works are all backwards compatible with the existing stuff. Thus, we would like to propose that the branch HBASE-7912 be merged into master. The parent jira has a design doc that goes into details about the implementation and design choices in case you are interested[2]. Most of the changes are largely non-intrusive and confined to the backup subsystem. The unit tests have been passing on manual runs and we (hortonworks) have been running the integration tests as well as some other shell-based system tests on a forked version of the code. Most of the work has been reviewed by 1, 2 or 3 committers already (mostly Ted, myself and Jerry). What do you guys think? Is it time to call a vote? Any concerns or feedback appreciated.
