(Updated Oct. 4, 2017, 12:16 a.m.)
Review request for mesos and Jie Yu.
Changes
-------
Addressed review comments.
Summary (updated)
-----------------
Added CatchupMissing log process.
Bugs: MESOS-7973
https://issues.apache.org/jira/browse/MESOS-7973
Repository: mesos
Description (updated)
-------
The process is used to catch-up a non-leading VOTING replica by running
the recovery protocol to find current begin and end positions of the log
and catching-up positions that are missing on the replica. This allows
following replicas to serve eventually consistent reads.

Testing
-------
Added tests that verify that the new recovery process correctly performs and
produces meaningful result under various circumstances (recovered positions
were truncated, replica was lagging far behind). Ran `make check`.
