Jesse Yates commented on HBASE-6573:
------------------------------------
Switching this to be a Three-Phase (rather than Two-Phase) commit and making it
a framework for orchestrating distributed commits. After Jon's comments and
talking with Lars H. about what would be nice to have pulled out of snapshots,
it made more sense to abstract out the entire control mechanism into the
general process with interfaces for additional orchestration (currently just
ZooKeeper, but could easily be done with RPC too) and abstract worker-side
(cohort) processing it comes out to be a pretty clean abstraction. The downside
means rewriting a bit of the snapshot stuff, but that should results in at
least a page if not more less for review on that (HBASE-6055).
So anyways, new review is up, still at https://reviews.apache.org/r/6592/
> Distributed Three-Phase Commit framework.
