Dave Latham commented on HBASE-13262:
-------------------------------------
Should we put a warning somewhere (mailing list? book?) about this? Something
like:
IF (client OR server is <= 0.98.11/1.0.0) AND server has a smaller value for
hbase.client.scanner.max.result.size than client does, THEN scan requests that
reach the server's hbase.client.scanner.max.result.size are likely to miss
data. In particular, 0.98.11 defaults hbase.client.scanner.max.result.size to
2MB but other versions default to larger values, so be very careful using
0.98.11 servers with any other client version.
> ResultScanner doesn't return all rows in Scan

> Tried to write a simple Java client again 1.1.0-SNAPSHOT.
> * Write 1M rows, each row with 1 family, and 10 qualifiers (values [0-9]),
> for a total of 10M cells written
> * Read back the data from the table, ensure I saw 10M cells
> Running it against {{04ac1891}} (and earlier) yesterday, I would get ~20% of
> the actual rows. Running against 1.0.0, returns all 10M records as expected.
> [Code I was
> running|https://github.com/joshelser/hbase-hwhat/blob/master/src/main/java/hbase/HBaseTest.java]
> for the curious.
