If necessary, set the pxf_service_address global
configuration property to a hostname or IP address and port where you
have installed the PXF Hive plug-in. By default, the value is set to localhost:51200 .
SET pxf_service_address TO "hivenode:51200"

Hi Shikhar , Can you confirm the below 1.Are you able to query a normal pxf table (other than hctalog or hive one ) .You can create an external table in hdfs 2.Please stop the pxf services in all the nodes and kill if there are any orphan processes to the 51200 port .We need to see why the tomcat server is not spawning up . 3.Once you clear all the processes start pxf services in all the nodes and query the table back . 4.Please make sure you have installed hive-clients in all the pxf nodes to access hive data . 5.Also see whether you need to set pxf_service_address point to the hive metstore

Hi Piyush , You can login to the hawq segment server and can stop the segment with the following ssh hawq-segment su - gpadmin source /usr/local/hawq/greenplum_path.sh hawq stop segment If it still not getting stopped ,look for the orphan segment process in the server and manually kill it (ps -ef|grep postgres ) .It would be good to the check segment logs in the server for the details .

Kerberos and ssl are both protocols, Kerberos is an authentication protocol, but SSL is an encryption protocol.Having said that if you really want to secure your data at motion ,you may need to consider SSL option and for better authentication of clients kerberos would be the best .Also you can have both (ssl & kerberos ) set it up for hawq .
