Cannot install Hive?

ed_day — Mon, 29 May 2017 15:14:05 GMT

Hi.

I have reinstalled my cluster (HDP 2.6.0.3 (Ambari 2.5.0.3)) and cannot get hive to work. I removed it from one node and added it to another but it (hiverserver2) still won't start. I get this error:

resource_management.core.exceptions.ExecutionFailed: Execution of '/usr/jdk64/jdk1.8.0_112/bin/java -cp /usr/lib/ambari-agent/DBConnectionVerification.jar:/usr/hdp/current/hive-server2/lib/mysql-connector-java.jar org.apache.ambari.server.DBConnectionVerification 'jdbc:mysql://s1.royble.co.uk/hive?createDatabaseIfNotExist=true' hive [PROTECTED] com.mysql.jdbc.Driver' returned 1. ERROR: Unable to connect to the DB. Please check DB connection properties.java.sql.SQLException: Access denied for user 'hive'@'s2.royble.co.uk' (using password: YES)

I saw this solution, but I do not have the required file on my computer, and I think I am missing lots of Hive stuff, for example there are no hive* folders below usr/hdp . Any idea how I can get Hive installed correctly?

This Error "Access denied for user 'hive'@'s2.royble.co.uk' (using password: YES)" itself states that you are entering wrong password for hive user crerated in Mysql.

To solve this Login to mysql

mysql> drop database hive;

And retry the installation of Hive service in ambari.

You are getting Access Denied while accessing mysql. So looks like you have node set the PRIVILEGES properly inside the mysql DB.

Please see: https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.2.0/bk_ambari-reference/content/using_hive_with_mysql.html

 # mysql -u root -p
CREATE USER '<HIVEUSER>'@'localhost' IDENTIFIED BY '<HIVEPASSWORD>';
GRANT ALL PRIVILEGES ON *.* TO '<HIVEUSER>'@'localhost';
CREATE USER '<HIVEUSER>'@'%' IDENTIFIED BY '<HIVEPASSWORD>';
GRANT ALL PRIVILEGES ON *.* TO '<HIVEUSER>'@'%';
CREATE USER '<HIVEUSER>'@'<HIVEMETASTOREFQDN>' IDENTIFIED BY '<HIVEPASSWORD>';
GRANT ALL PRIVILEGES ON *.* TO '<HIVEUSER>'@'<HIVEMETASTOREFQDN>';
FLUSH PRIVILEGES;

Thanks I am not using mysql but derby. I tried switching to mysql using this, but I cannot ' Downloadmysql-connector-java-5.0.5.jar file and copy it to $HIVE_HOME/lib directory.' since I do not have such a directory!

The link that you shared to migrate from Derby to MySQL seems to be too old (2013) and there are many changes and enhancements made in hive.

I do not see "Derby" database in the supported list of Databases in: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.0/bk_support-matrices/content/ch_matrices-hdp.html So if this is your fresh cluster then you should install Hive with the supported databases to avoid the DB issues.

HDP 2.6 Hive Database Requirements

PostgreSQL 9.1.13+, 9.3, 9.4***
MariaDB 10*
MySQL 5.6****
Oracle 11gr2
Oracle 12c**
By default (on RHEL/CentOS/Oracle Linux 6), Ambari installs an instance of MySQL
                on the Hive Metastore host. Otherwise, you need to use an existing instance of
                PostgreSQL, MySQL or Oracle.

Thanks. I was getting confused: it was mysql all along.
