How can I see different version of Hbase data using Hive?

How can I see different version of Hbase data in Hive. As per my understanding using HbaseStorageHandler only latest version of Hbase data will be available in Hive .Is my understanding correct/updated?

Is there any way to access different version of Hbase data using Hive??

Thanks in advance :)

Not 100% answer but directions. In normal life HBase is always about special cases.

Here is slightly outdated but really simple article to understand approach: http://hortonworks.com/blog/hbase-via-hive-part-1/

So practically you can implement any InputFormat or OutputFormat you need. But this is related to MapReduce gears.

In principle Spark can always rely on InputFormat too so the question is only about your special case.

Another good idea is depicted here: http://www.slideshare.net/HBaseCon/ecosystem-session-3a So snapshots could help to take state of tables you really need and then you are free to use any gear to connect Hive with HBase if it follow standards.

In general basic idea is to tune gears which connects Hive to your HBase data so they will apply needed version filters to you. This does not depend so much on versions as this interface is pretty stable.

Hope this will help you.

That would depend on the version of hive that you are using. Prior to hive 1.1, hbase timestamps were not accessible through the hive-hbase integration [1] (Related: [2]). So the answer being, You require hive 1.1 or higher. Hope it helps.
