[jira] [Created] (HBASE-20951) Ratis LogService backed WALs

Josh Elser created HBASE-20951:
----------------------------------

             Summary: Ratis LogService backed WALs
                 Key: HBASE-20951
                 URL: https://issues.apache.org/jira/browse/HBASE-20951
             Project: HBase
          Issue Type: New Feature
          Components: wal
            Reporter: Josh Elser
            Assignee: Josh Elser


Umbrella issue for the Ratis+WAL work:

Design doc: [https://docs.google.com/document/d/1Su5py_T5Ytfh9RoTTX2s20KbSJwBHVxbO7ge5ORqbCk/edit#|https://docs.google.com/document/d/1Su5py_T5Ytfh9RoTTX2s20KbSJwBHVxbO7ge5ORqbCk/edit]

The (over-simplified) goal is to re-think the current WAL APIs we have now, ensure that they are de-coupled from the notion of being backed by HDFS, swap the current implementations over to the new API, and then wire up the Ratis LogService to the new WAL API.
