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.
