> Coordination Engine (CE) is a system, which allows to agree on a sequence of events in
a distributed system. In order to be reliable CE should be distributed by itself.
> Coordination Engine can be based on different algorithms (paxos, raft, 2PC, zab) and
have different implementations, depending on use cases, reliability, availability, and performance
requirements.
> CE should have a common API, so that it could serve as a pluggable component in different
projects. The immediate beneficiaries are HDFS (HDFS-6469) and HBase (HBASE-10909).
> First implementation is proposed to be based on ZooKeeper.
