Ambari-server start error

New Contributor

I am trying to install HDP 3.1 with Ambari 2.7 following this document https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.3.0/bk_ambari-installation/content/set_up_the_a...

All software installation completed and mysql database had been created. I then setup ambari with "ambari setup" followed by "ambari start". But I got follwing errors. I had listed the screen output for ambari setup and part of ambari-server.log to show the error message. Please help.

 

Thanks,

Harry

So is your Ambari Server running fine now?  Please share the ambari server log if you see the same MySQL error.

Also for tested and certified version of MySQL that can be used with Ambari please refer to the following link :  https://supportmatrix.hortonworks.com/

Looks like due to some issue Ambari is not able to connect to MySQL and hence the Connection Pool is not getting populated.

Most probably it might be some issue with MySQL / Network issue (firewall..etc)/ Misconfiguration like incorrect host/port in ambari configs for MySQL host/port ...etc

So can you please test the connection by running this simple command from ambari server host to see if you get a Successful connection creation response?

# /usr/jdk64/jdk1.8.0_112/bin/java -cp /var/lib/ambari-server/resources/DBConnectionVerification.jar:/usr/share/java/mysql-connector-java.jar org.apache.ambari.server.DBConnectionVerification "jdbc:mysql://xxxxxxxxxxx:3306/ambari" "ambari" "bigdata" com.mysql.jdbc.Driver



Please use your own MySQL username and passwords in the above query to test the connection. I am using default password as "bigdata" and DB user name as "ambari" in the above example query.

If it fails to connect to mysql then Pleas echeck if at n/w level the Port access is allowed to MySQL Server from Ambari Server host?

# telnet $MYSQL_FQDN 3306
(OR)
# nc -v $MYSQL_FQDN 3306

 

If possible then can you please try restarting your MysQL server once and then retry.

Thanks for the quick response. I had firewall disabled and nc -v command seems working.

From command line, I can access the mysql. See below for detail

@harry_li 

So is your Ambari Server running fine now?  Please share the ambari server log if you see the same MySQL error.

Also for tested and certified version of MySQL that can be used with Ambari please refer to the following link :  https://supportmatrix.hortonworks.com/
