             Summary: Untangle region - region server dependencies
                 Key: HBASE-14055
                 URL: https://issues.apache.org/jira/browse/HBASE-14055
             Project: HBase
          Issue Type: Sub-task
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar
             Fix For: 2.0.0, 1.3.0


We need to untangle region from outside of region server. The parent jira is trying to create an embedded library, like leveldb, out of region so that it should be possible to host a set of regions without being a regionserver. 

>From a layering point of view, region hosting and WAL services should be abstracted. Hosting a region means threads for flushing, compaction, cleanups, hosting a WAL, and block cache. The RegionServer normally holds these, together with RpcServer and zk connection, heartbeats, and all other stuff that is required for running as a deamon and inside a cluster. 

See parent jira for some more context.
