Summary: Write the last sequence id into the HLog during the
RegionOpen time
Key: HBASE-10343
URL: https://issues.apache.org/jira/browse/HBASE-10343
Project: HBase
Issue Type: Improvement
Reporter: Liyin Tang
HLog based async replication has a challenging to guarantee the in-order
delivery when the Region is moving from one HLog stream to another HLog stream.
One approach is to keep the last_sequence_id in the new HLog stream when
opening the Region. So the replication framework is able to catch upto the
last_sequence_id from the previous HLog stream, before replicating any new
transactions through the new HLog stream.
