> Key: HBASE-10578
> URL: https://issues.apache.org/jira/browse/HBASE-10578
> Project: HBase
> Issue Type: Bug
> Components: Scanners
> Affects Versions: 0.89-fb, 0.98.1
> Reporter: Amitanand Aiyer
> Assignee: Amitanand Aiyer
> Priority: Minor
> Fix For: 0.89-fb
>
> Attachments: HBASE-10578.patch
>
>
> When multiple scanners have the same KV, HBase should pick the "newest" one.
> i.e. pick the KV from the store file with the largest seq id.
> In the KeyValueHeap generalizedSeek implementation, we seem to prefer the
> "current"
> scanner over the scanners in the heap -- THIS IS WRONG.
> The diff adds a unit test to make sure that bulk loads correctly. And fixes
> the issue.
