Apekshit 11740570c1 HBASE-15236 Inconsistent cell reads over multiple bulk-loaded HFiles. In KeyValueHeap, if two cells are same i.e. have same key and timestamp, then instead of directly using seq id to determine newer one, we should use StoreFile.Comparater.SEQ_ID because that's what is used to determine order of hfiles. In this patch, we assign each scanner an order based on it's index in storefiles list, which is then used in KeyValueHeap to disambiguate between same cells. Changes the getSequenceId() in KeyValueScanner class to getScannerOrder(). Testing: Adds unit test to TestKeyValueHeap. Manual testing: Three cases (Tables t, t2, t3 in the jira description), single region, 2 hfiles with same seq id, timestamps and duplicate KVs. Made sure that returned kv was same for get and scan.
