Hive 0.9 with HBase 0.90

Hive 0.9.0 was released at the beginning of this month and it contains a lot of very nice improvements. Thanks to all involved!

Unfortunately it drops compatibility with HBase 0.90.x due to two issues which introduced a dependency on HBase 0.92:
Fortunately these were relatively easy to revert so that's what we did because we wanted to all the 0.9.0 goodness on our HBase 0.90.4 cluster (CDH3u3).

I've forked Hive on Github and reverted the parts of those two issues (HIVE-2748, HIVE-2764) that were causing problems.

For all those "stuck" with HBase 0.90 (e.g. CDH3 users) we've also deployed this custom Hive HBase Handler to our own Maven repository and will maintain that for the foreseeable future. You can just download the jar file and use it in your projects or use our Maven repository:


And then declare a dependency on this custom HBase Handler:


Note for Maven experts: I'm not sure if this is a valid classifier. I couldn't find any naming rules.

That's it! We might maintain this for future versions of Hive but we'd love to hear about any problems in any case.


  1. Thank you very much.
    You saved me.

  2. Thanks for this sharing. I downloaded your custom handler jar and placed it in hive's lib directory. Deleted old handler jar and changed hive.aux.jars.path parameter accordingly. But i am getting following error:

    hive> show tables;
    FAILED: Error in metadata: MetaException(message:Got exception: javax.jdo.JDOFatalInternalException JDBC type integer declared for field "org.apache.hadoop.hive.metastore.model.MTable.createTime" of java type java.lang.Integer cant be mapped for this datastore.)
    FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

    have you ever run into this issue?
