Andrew Purtell updated HBASE-12988:
-----------------------------------
Attachment: HBASE-12988-0.98.patch
I applied the attached backport patch for 0.98 to the head of 0.98 branch, set
up two single master single RS clusters, then ran IntegrationTestReplication
without YARN (so, LocalTestRunner). All test parameters were defaults. This
used to work - by accident, frankly, since verification would manage to stay
behind where replication was at - but now because edits will be shipped out of
order we definitely have to wait for that to finish before verification can
commence. I'm happy to say though that after replication has synced all changes
verification will pass, so the changes here do not cause any data loss.
