---------------------------------------
Summary: Hive replication cause file copy failures if HDFS block
size differs across clusters
Key: HIVE-19248
URL: https://issues.apache.org/jira/browse/HIVE-19248
Project: Hive
Issue Type: Bug
Components: HiveServer2, repl
Affects Versions: 3.0.0
Reporter: Sankar Hariappan
Assignee: Sankar Hariappan
Fix For: 3.1.0
This is the case where the events were deleted on source because of old event
purging and hence min(source event id) > target event id (last replicated event
id).
Repl dump should fail in this case so that user can drop the database and
bootstrap again.
Cleaner thread is concurrently removing the expired events from
NOTIFICATION_LOG table. So, it is necessary to check if the current dump missed
any event while dumping. After fetching events in batches, we shall check if it
is fetched in contiguous sequence of event id. If it is not in contiguous
sequence, then likely some events missed in the dump and hence throw error.
