--------------------------------------------
Summary: Introduce Coordination Engine
Key: HADOOP-10641
URL: https://issues.apache.org/jira/browse/HADOOP-10641
Project: Hadoop Common
Issue Type: New Feature
Affects Versions: 3.0.0
Reporter: Konstantin Shvachko
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.
