Issue in adding Hive service from ambari in HDP 2.5

avatar
Expert Contributor

Hi Team,

We have set up a 3 node HDP 2.5 cluster using CentOS 6.5. When we are trying to add the Hive service from Ambari in that cluster we are receiving connection refused error (error happening in all the 3 nodes). However, we have successfully added other services without any issues. Please note that while adding service we are selecting New MySQL database, there is no existing MySQL database in that cluster. Need your help to address the issue. Error stack given below which came under "Hive Client Install" while adding the Hive service.

Traceback (most recent call last):

It should download DBConnectionVerification.jar from Ambari server. I just double checked. Not sure why it is picking up different host instead of Ambari server. Can you please check your /etc/hosts file just to see if there is any conflicting entry.

This problem is happening while installing hive-client on your system.

Can you please make sure to have DBConnectionVerification.jar on all the ambari-agents?

/usr/lib/ambari-agent/DBConnectionVerification.jar
/var/lib/ambari-agent/tmp/DBConnectionVerification.jar

Typically, on Ambari server, below is the location for DBConnectionVerification.jar

/var/lib/ambari-server/resources/DBConnectionVerification.jar

Please note that all the pre-requisites like SSH setup, THP disable, SELinux disable, iptables disable have been done in all the nodes in the cluster.

Hi,

Please check ambari server log file and also verify the ports are open for MYSQL 3306 on that host.

Hi,

Ambari server log snippet below and 3306 port is open.

On which host you have installed MySQL server? Can you please double check if MySql is up and running? Can you also try to login to mysql shell from any other node in the cluster and see if its working?

Hi @Kuldeep Kulkarni.....we are selecting new MySQL instance while adding the Hive service so MySQL is not pre-configured. We have deleted the service from Ambari as Hive services are having issues.

@rajdip chaudhuri - Okay below command is failing:

Downloading the file from http://dn1.tcsgegdc.com:8080/resources/DBConnectionVerification.jar

Can you please make sure that you are able to connect to Ambari server from problematic host where above command is failing? you can try simple telnet to check the connectivity on port 8080
