Nick Dimiduk updated PHOENIX-971:
---------------------------------
Attachment: PHOENIX-971.00.patch
Here's a simple patch for Phoenix that adds a query server and thin client via
Apache Calcite. Most of the good work has been happening over on the Calcite
side (thanks [~julianhyde]!). This patch is building from a Calcite snapshot
based on a couple outstanding patches on [my
branch|https://github.com/ndimiduk/incubator-calcite/tree/avatica-to-prod].
The server is launched using bin/queryserver.py, which depends on having
HBASE_CONF_PATH in the environment to find hbase-site.xml. You can then use
bin/sqlline-thin.py to connect using the thin driver. The same arguments should
work as with the regular one, the difference being that instead of a zookeeper
quorum, you point it at the query server host and port (i.e.,
http://localhost:8765). It will add any missing connection components based on
defaults.
Also note that select * from WEB_STATS example table does not work right now
due to a known Date datatype handling bug, CALCITE-660. Other common column
types are working.
[~jamestaylor] [~gabriel.reid] please have a look, in particular at my
additions to the maven structure and new .py scripts.

> Host the JDBC driver in a query server process that can be deployed as a
> middle tier between lighter weight clients and Phoenix+HBase. This would
> serve a similar optional role in Phoenix deployments as the
> [HiveServer2|https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2]
> does in Hive deploys.
