Lars Hofhansl commented on HBASE-13262:
---------------------------------------
Without looking at the patch... I do not think this issue needs an extensive
fix. We only need to do the following:
# add an "exhausted region" bit to the scan response
# on the server set that flag if we sent a response because we ran out of stuff
to read from the region (i.e. we did *not* run into a size or row limit).
# on the client, if present, use this bit to decide how to continue in the
loop. I.e. if set skip to the next region (else fall back to the existing
logic, in all versions but trunk)
I wouldn't do more in this jira. Fix the basic stuff first, then file add-on
jiras to improve.
It's also quite possible that I am missing something.

> 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.
