I have recently spent several days trying to run the phoenix thin (queryserver.py and sqlline-thin.py) and thick via zookeeper to secure cluster.But, I could not able to start or connect the phoenix service on secure cluster.

Faced Below issues on phoenix thin and thick clients

sqlline version 1.2.0
0: jdbc:phoenix:Namenode1>

Followed below steps

  1. Removed the hbase-site.xml file on phoenix and set the HBase package environment.

  2. Provided the Kerberos principal and keytab for the Phoenix Query Server in the $HBASE_CONF_DIR/hbase-site.xml file.

    phoenix.queryserver.kerberos.principal HTTP/webuser@Domain.COM

    phoenix.queryserver.kerberos.keytab
    C:\KeyTab\webuser.keytab

  3. Execute thin server and Client by

    a. Start Query server - /bin>python queryserver.ph which started properly.

    b. Start thin client - /bin>python sqlline.py http://namenode1:8765;authentication=SPENGO;principal=HTTP/webuser@Domain.COM;keytab=C:\\KeyTab\\webuser.keytab

4.Execute on Thick client by below commands

/bin> python sqlline.py Namenode1:2181:/hbase-secure:HTTP/webuser@Domain.COM:C:\\KeyTab\\webuser.keytab

Let me know, Any other configurations are required an Apache phoenix with secure cluster.

  • you may want to turn advanced tracing on and check that it is picking up the hbase-site.xml from HBASE_CONF, we've had to copy into the bin directory for phoenix a number of times. – Paul Bastide Sep 27 '17 at 11:14
  • @paulBastide. Can you give brief explanation. – BASS KARAN Sep 27 '17 at 11:48
