[jira] Commented: (HADOOP-2197) [hbase] Allow user add arbitrary key/value pairs to table and column descriptors

["Vuk Ercegovac (JIRA)" <ji...@apache.org>]

Vuk Ercegovac commented on HADOOP-2197:
---------------------------------------

A possibility is to use a language neutral format such as JSON.
A collection of key/value pairs would then simply be called an "object".
Furthermore, this should integrate well with jaql, a query language we recently announced
for JSON data and posted further information at http://www.jaql.org.
In fact, we've implemented several functions in the language to manage HBase data.
As a result, type information, through the use of JSON, is serialized into HBase byte array column values.
We did not consider descriptions for tables, but I suppose this is reasonable to store in the catalog.
