> The storeFileScanner's seekAtOrAfter method will position at the beginning of
> the file when the passed KV is smaller than first KV in file. While for
> reseekAtOrAfter, I think it should also do the same thing when it is the
> first time it been seeked. originally, this is workaround by adding a
> isReseekable property in StoreFileScanner, and is checked upon each
> enforceSeek(), if it is not seeked before, it will go with seek approaching
> instead of reseek approaching. While why not make reseekAtOrAfter working
> correctly for the first time it been reseek (also never been seek before),
> since the file is never seeked before, so position it at the beginning of the
> file don't break the idea of "reseek", say never rewind.
> It will save the effort for HBASE-8001, with this fixed, it won't need to
> check isReseekable any more.
