Jim Kellerman commented on HBASE-686:
-------------------------------------

This patch is listed as affecting hbase-0.1.2, but the APIs you are using only 
exist in trunk (0.2.0) is this issue for 0.1.2 or for 0.2.0?

> MemcacheScanner didn't return the first row(if it exists), cause 
> HScannerInterface's output incorrect

> 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.
