perhaps not SQL/JDBC but a query language like HQL.
since there are many comparisons betwen HBase and google bigtable, i was hoping
for a query capability found in GAE.
http://code.google.com/appengine/docs/datastore/queriesandindexes.html
# The GqlQuery interface prepares a query using a GQL query string.
q = db.GqlQuery("SELECT * FROM Person " +
"WHERE last_name = :1 AND height < :2 " +
"ORDER BY height DESC",
"Smith", 72)
as u can see the query language is very similar to SQL and easy to use.

i have read the docs and was hoping for GAE like functionality to access the
datastore.
so my questions are
1) why is having a query language mutual exclusive to HBase goals?
2) what is the expected integration point to a J2EE appllication for HBase?
any help is appreciated.
