Just to clarify, like near all other services on Linux, you do not want
to run the Phoenix Query Server as root. Running it as the "hbase" user
(or the user you are running hbase as) is the common way to do this.

OK, this means you probably don't have Phoenix query server started.
I'm not a cloudera distro expert, but I assume you can locate this file
"queryserver.py"
Run
$>sudo ./queryserver.py start
And try curl again
For more details:

Don't hesitate to reach out if you run into more roadblocks.

Hi Will,
curl http://localhost:8765
curl: (7) Failed to connect to localhost port 8765: Connection refused
How I open this connection?

A few things.
1. Are you on 0.5 version of the connector?
$>pip freeze | grep phoenixdb
Should be==> phoenixdb==0.5
2. Can you try curl http://localhost:8765 to see if the server is
actually running? If you open the page in browser you should see a
Jetty 404 page.
PQS is a think wrapper around Phoenix client. It's actually a
service. If you have sqlline-thin client you can test it out.
$>bin/sqlline-thin.py http://localhost:8765

I followed the instruction from
http://python-phoenixdb.readthedocs.io/en/latest/
<http://python-phoenixdb.readthedocs.io/en/latest/>
to connect Hbase in cloudera cluster, but I got the following error
below.
>>> import phoenixdb
>>> database_url = 'http://localhost:8765/'
>>> conn = phoenixdb.connect(database_url, autocommit=True)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

line 152, in connect
raise errors.InterfaceError('Unable to connect to the specified

phoenixdb.errors.InterfaceError: ('Unable to connect to the
specified service', error(111, 'Connection refused'), None, None)
I can create table using phoenix-sqlline.py localhost:2181:/hbase or
even use ./psql.py to import CSV, why the python adaopter does not
work? Could someone give me a simple example that allows the adapter
to connect Hbase in Cloudera?
I've been trying to find the solution for days... please help!
