Hi,
I've installed Phoenix Query Server (PQS) on one of the nodes on my cluster based on this answer.
At first, it's running, but when I restart the HBase, PQS wont start again. Here's the error log below:
On the node where PQS is installed, I also installed "clients".
Also, when installing PQS, do I need to enable Phoenix? or This will be automatic after PQS install?
Thank you in advance!

It seems that PQS is already running with the pid 6896. You may try to use it just running thin client.

You should enable Phoenix - Josh please correct me if I am wrong.
Can you use jps command to see if the previous PQS server was stopped ?
How did you restart the cluster ?

Hi @Ted Yu, thanks for the respose.
1. Noted on enabling phoenix
2. JPS
6896 Main 7731 NiFi 32283 Kafka 22044 ConsoleConsumer 1740 jenkins.war 7709 RunNiFi 28271 Jps
3. I didn't restart the whole cluster. Just restarted hbase component. Restarted it via Ambari

Below steps might help you:
If you are running external applications, it is recommended that you test the connection to HBase using the following connection strings for the Phoenix JDBC driver:
set CLASSPATH=<path_to_hbase-site.xml>;<path_to_core-site.xml> i.e. export HBASE_CONF_PATH=/etc/hbase/conf:/etc/hadoop/conf
jdbc:phoenix:<Zookeeper_host_name>:<port_number>:<root_node>
Where <Zookeeper_host_name
> can specify one host or several hosts. If you specify several Zookeeper hosts, insert commas between host names. For example, <ZK_host1, ZK_host2, ZK_host3>.
Example:
jdbc:phoenix:zk_quorum:2181:zk_parent (or) if you are logged in as your own user kinit /usr/hdp/current/phoenix-client/bin/sqlline.py hostname.domain.com:2181:/hbase-secure
jdbc:phoenix:<Zookeeper_host_name>:<port_number>:<secured_Zookeeper_node>:<principal_name>:<HBase_headless_keytab_file>
Where <secured_Zookeeper_node
> is the path to the secured Zookeeper node, and <HBase_headless_keytab_file
> is the location of this keytab file.
Example:
jdbc:phoenix:zk_quorum:2181:/hbase-secure:hbase@EXAMPLE.COM:/hbase-secure/keytab/keytab_file (or) if using logged in as hbase user kinit -k -t /etc/security/keytabs/hbase.headless.keytab hbase /usr/hdp/current/phoenix-client/bin/sqlline.py hostname.domain.com:2181:/hbase-secure:hbase@domain.com:/etc/security/keytabs/hbase.headless.keytab

Thanks @Sri Bandaru. Will take note on this.

Just did run phoenix-sqlline and it's working.
mmmm.. I'll try to kill it and restart the PQS.
thanks @ssoldatov

The phoenix-sqlline command is not using PQS. You want to use /usr/hdp/current/phoenix-client/bin/sqlline-thin.py to interactive with PQS.

You can restart PQS using Ambari.
