Mikhail Bautin commented on HBASE-6562:
---------------------------------------
[~lhofhansl]: the easiest way would be to disable lazy seek for such queries
and document it. I'm not sure what the exact set of filters that conflict with
lazy seek is, though.

> In internal tests at Salesforce we found that fake row keys sometimes are
> passed to filters (Filter.filterRowKey(...) specifically).
> The KVs are eventually filtered by the StoreScanner/ScanQueryMatcher, but the
> row key is passed to filterRowKey in RegionScannImpl *before* that happens.
