> 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.
