> Avoid next operations (and instead reseek) when current kv is deleted

> Key: HBASE-4585
> URL: https://issues.apache.org/jira/browse/HBASE-4585
> Project: HBase
> Issue Type: Improvement
> Reporter: Liyin Tang
> Assignee: Liyin Tang
> Fix For: 0.94.0

> Attachments: hbase-4585-89.patch, hbase-4585-apache-trunk.patch

>
> When the current kv is deleted during the matching in the ScanQueryMatcher,
> currently the matcher will return skip and continue to do next() instead of
> reseeking to the next column of interest.
> Actually, if the current kv is deleted because of family deleted or column
> deleted, the matcher should seek to next col.
> If the current kv is deleted because of version deleted, the matcher should
> just return skip.
