-------------------------------------
Upload backport patch for 3.0 to check seek hint order with in column family
which I will commit this after some time.
[~lhofhansl]
bq. I meant RegionScanner, sorry. (unless we have multiple column families
Region == Store as far as this discussion is concerned).
Ohh. no problem.
bq. Why are we seeking to seemingly the same position again?
(prev=varchar7//LATEST_TIMESTAMP/Maximum/vlen=0/mvcc=0,
next=varchar7//LATEST_TIMESTAMP/Maximum/vlen=0/mvcc=0) Do you have multiple
column families in your case?
Yes Lars there are two column families in the table. Currently reseek happening
on only one store scanner at a time so even after first store scanner reseek to
varchar7 second store scanner still scans kvs less than hint, that's why same
hint given by filter. In latest patch checking seek hint order column family
wise.
Thanks.

> After checking in a pretty sizeable change
> (https://git-wip-us.apache.org/repos/asf?p=phoenix.git;a=commit;h=d018cc1c6e01d9836de6e67af4f8b91de3269bfd),
> the assert in SkipScanFilter.setNextCellHint() started getting tripped for
> the following unit tests:
> - DeleteIT.testDeleteAllFromTableWithIndexNoAutoCommitNoSalting()
> - MutableIndexIT.testCoveredColumnUpdatesWithLocalIndex()
> The tests seem to pass without this assert (not sure what HBase does if the
> seek next hint is the same as the current row), but it would be good to get
> to the bottom of this. Would you mind taking a look, [~rajesh23]? It's
> possibly related to PHOENIX-1313.
