[jira] Commented: (HIVE-1245) allow access to values stored as non-strings in HBase

["John Sichi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-1245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12886541#action_12886541 ] 

John Sichi commented on HIVE-1245:
----------------------------------

For atomic types, we could extend the column-level mapping directive to allow for three options

* string
* binary
* use table-level default

So where we currently have a:b, we would support a:b:string and a:b:binary.

The table-level default would be set in a separate serde property hbase.storedtype.atomic, with a default value of string for backwards-compatibility.

Then something similar for compound types, but with json and delimited as options?  I haven't thought about all the combinations, and what to do with column familiies.
