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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
