Created ‎05-10-2019 01:09 PM

Hello HW community,
I have a problem with my HiveMetastore & Hiveserver2 dont start at all due to the database connexion with the jdbc driver.
i proprelly executed the "https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.5/bk_ambari-administration/content/using_hive... " i have the 3 hive users on mysql, i created the hive database and linked the mysql-connector-java.jar to my ambari-server. I tried some solution kind of replace the "localhost" in the Database URL by the host name or the ip address too, but same error.

PS: all the others services are turning.

My error is :

stderr:

@Adil BAKKOURI

Hurrah we are now there, thats the error I was expecting now this is a case closed.

Validate the hostname by running

# hostname -f

This should give you the FQDN

The error below is very simple its a privilege issue with the hive user and database creation script you run, you didn't give the correct privileges to the hive user "Access denied for user 'hive'@'master.rh.bigdata.cluster' to database 'hive'"


To resolve the above please do the following assumptions

Root password = gr3atman

Hive password = hive

Hostname = master.rh.bigdata.cluster

mysql -uroot -pgr3atman
mysql> GRANT ALL PRIVILEGES ON hive.* to 'hive'@'localhost' identified by 'hive';
mysql> GRANT ALL PRIVILEGES ON hive.* to 'hive'@'master.rh.bigdata.cluster' identified by 'hive';
mysql> GRANT ALL PRIVILEGES ON hive.* TO 'hive'@'master.rh.bigdata.cluster';
mysql> flush privileges;


All of the above should succeed. Now your hive should fire up Bravo !!

@Adil BAKKOURI

The below error tells me 2 things you are either using a MySQL server which is not supported or your jdbc driver version is not correct can you validate your Mysql database against the HXW support matrix


2019-04-16 15:55:44,477 - Check db_connection_check was unsuccessful.

Exit code: 1. Message: Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'.

The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

ERROR: Unable to connect to the DB. Please check DB connection properties. com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

@Adil BAKKOURI

Can you firstly stop/ re-run ambari with the below command


ambari-server stop

Then

ambari-server start --skip-database-check

Your Ambari database has many orphaned config please see this Jira how to clean you Ambari database though it would be faster to start with a clean installation but it good to get your hands dirty !!!

https://issues.apache.org/jira/browse/AMBARI-20875


CREATE TEMPORARY TABLE IF NOT EXISTS orphaned_configs AS (SELECT cc.config_id, cc.type_name, cc.version_tag FROM clusterconfig cc, clusterconfigmapping ccm WHERE cc.config_id NOT IN (SELECT scm.config_id FROM serviceconfigmapping scm) AND cc.type_name != 'cluster-env' AND cc.type_name = ccm.type_name AND cc.version_tag = ccm.version_tag);

Followed by

DELETE FROM clusterconfigmapping WHERE EXISTS (SELECT 1 FROM orphaned_configs WHERE clusterconfigmapping.type_name = orphaned_configs.type_name AND clusterconfigmapping.version_tag = orphaned_configs.version_tag);

Followed by

DELETE FROM clusterconfig WHERE clusterconfig.config_id IN (SELECT config_id FROM orphaned_configs);

Followed by

SELECT * FROM orphaned_configs;

Then 

DROP TABLE orphaned_configs;


Now you Ambari db should be clean to proceed with the hive setup

@Adil BAKKOURI

The attached /var/log/ambari-server/ambari-server-check-database.log shows you are trying to connect to postgres which is the embedded database.

My guess is your ambari Server is using the embedded postgres database and NOT MySQL so what you need to do after installing and configuring MySQL and Hive is

Install the mySQL driver adapt the commands according to your OS

yum install -y mysql-connector-java

Make the jars available for hive etc this won't effect the Postgres installation

ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar

Now continue with the Ambari hive setup it should succeed NOW!!!!

Hi Geoffrey Shelton Okot ,

first I want to thank you for your answer,

I deleted hive and restarted all instalations and configurations as you said and the tuto explain but still the same error at the end.

Here some screenshoots of the conf:

mysql and systeme time : 107943-time-mysql.jpg

user and database on mysql :


107922-usr-database-mysql.jpg

hive conf on ambari :

107953-hive-conf.jpg




I found this warning on /var/log/ambari-server/ambari-server-check-database.log :

107938-checkdb-mysql.jpg

@Adil BAKKOURI

You have done everything correctly but you are not selecting the existing database you created 🙂 See attached screenshot all should work !!!

107954-mysql-hive-setup.png

Please use the values of the hive DB created previously it should pick the correct URL and host !!
