Description

Some rows is missing when put them into a table using mutateRow method and each row has thousands of columns. The code excerpt:

try (HConnection hc = HConnectionManager.createConnection(conf)) {
	try (HTableInterface table = hc.getTable(tableName)) {
		final LocalDate startDate = LocalDate.of(1980, 01, 01); 
		for (int i = 0; i < 15000; i++) {
			byte[] row = Bytes.toBytes(Integer.toString(i));

			long ts = System.currentTimeMillis();
			Put put = new Put(row, ts + 1);
			LocalDate date = startDate; 
			for (int j = 0; j < 5000; j++) {
				put.add(
					family,
					Bytes.toBytes(DateTimeFormatter.BASIC_ISO_DATE.format(date)),
					Bytes.toBytes(Integer.toString(j))
				);
				date = date.plusDays(1);
			}
			
			RowMutations rm = new RowMutations(row);

			rm.add(put);
			
			table.mutateRow(rm);
		}
	}
}

Resulting number of rows varies - sometimes it 200, sometimes it 8000. But never expected 15000.
The full code of test application is attached.
