Sergey Shelukhin updated HBASE-10242:
-------------------------------------
Attachment: HBASE-10241.wip0.patch
WIP patch. It already works for restricted reopen scenarios (see hack in test);
for split it doesn't work so far because server part is not implemented, so
compaction does not preserve mvcc.
TODOs:
- rig the test for splits and merges to work
- make work in reverse scanner (not needed for small scanner?)
- make the new public methods private for now if this is to be committed
before the server part. Or they can go in together, this is not needed.
> client-side mvcc tracking in scanners

> Scanners should be able to track mvcc read point and send it to server. This
> is a subtask, so server can use this mvcc as best it can, but doesn't
> actually have to guarantee it within the scope of this jira.
