> --------------------------------------------------------
>
> Key: HIVE-3399
> URL: https://issues.apache.org/jira/browse/HIVE-3399
> Project: Hive
> Issue Type: Improvement
> Components: HBase Handler
> Affects Versions: 0.10.0
> Reporter: Navis
> Assignee: Navis
> Priority: Minor
>
> Currently, RecordReader.getPos() for hbase handler returns always zero and
> it's not wrong in the sense that it's not clear how to calculate it(as
> specified in hbase javadoc).
> But if getPos() returns some meaningful value, it can make percent table
> sampling in HIVE-2925 possible to be used, which seemed very useful.
