Subject [jira] [Commented] (HIVE-7068) Integrate AccumuloStorageHandler
Date Fri, 15 Aug 2014 21:41:19 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7068?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14099196#comment-14099196

Josh Elser commented on HIVE-7068:
----------------------------------

[~ndimiduk], I agree with you completely. There's no reason that the column mapping stuff
needs to be separated as it is now. I tried to make the ColumnMapping class hierarchy a bit
cleaner over what was in the hbase-handler (it looked like there were already comments in
the hbase-handler code saying that it would be good to clean it up in the future). I'd love
to help converge these.

Many thanks for taking the time to look through it.

> [Accumulo|http://accumulo.apache.org] is a BigTable-clone which is similar to HBase.
Some [initial work|https://github.com/bfemiano/accumulo-hive-storage-manager] has been done
to support querying an Accumulo table using Hive already. It is not a complete solution as,
most notably, the current implementation presently lacks support for INSERTs.
> I would like to polish up the AccumuloStorageHandler (presently based on 0.10), implement
missing basic functionality and compare it to the HBaseStorageHandler (to ensure that we follow
the same general usage patterns).
> I've also been in communication with [~bfem] (the initial author) who expressed interest
in working on this again. I hope to coordinate efforts with him.
