[jira] [Updated] (HIVE-3399) Support split sampling for tables on
hbase in fetch mode
[ https://issues.apache.org/jira/browse/HIVE-3399?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Navis updated HIVE-3399:
------------------------
Summary: Support split sampling for tables on hbase in fetch mode (was: Support getPos() for hbase record reader )
> Support split sampling for tables on hbase in fetch mode
> --------------------------------------------------------
>
> Key: HIVE-3399
> URL: https://issues.apache.org/jira/browse/HIVE-3399
> Project: Hive
> Issue Type: Improvement
> Components: HBase Handler
> 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.
