> HTable.obtainScanner methods should return the start row if it exists,
> although HTable's javadoc didn't clearly desc. but i found the result of
> htable scanners sometimes contain the start row, sometimes not.
> after more testing and code review, i found it should be a bug in
> HStore.Memcache.MemcacheScanner. in the constructor it set this.currentRow =
> firstRow, but when doing next(), there's a this.currentRow =
> getNextRow(this.currentRow) before fetch result.
