On the Hive Metastore machine, install the appropriate JDBC .jar file:
For Oracle:
Download the Oracle JDBC (OJDBC) driver from http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html.
Select Oracle Database 11g Release 2 - ojdbc6.jar
Copy the .jar file to the Java share directory
cp ojdbc6.jar /usr/share/java
Make sure the .jar file has the appropriate permissions - 644.
For MySQL:
Install the connector.
RHEL/CentOS
yum install mysql-connector-java-5.0.8-1
SLES
zypper install mysql-connector-java-5.0.8-1
Confirm that the MySQL .jar file is in the Java share directory
ls /usr/share/java/mysql-connector-java.jar
Make sure the .jar file has the appropriate permissions - 644.
Create a user for Hive and grant it permissions:
For Oracle, create the Hive user and grant it database permissions:
# sqlplus sys/root as sysdba SQL> CREATE USER $HIVEUSER IDENTIFIED BY $HIVEPASSWORD; SQL> GRANT SELECT_CATALOG_ROLE TO $HIVEUSER; SQL> GRANT CONNECT, RESOURCE TO $HIVEUSER; SQL> QUIT;
Where
$HIVEUSER
is the Hive user name and$HIVEPASSWORD
is the Hive user password.For MySQL, create the Hive user and grant it database permissions
# mysql -u root -p mysql> CREATE USER ‘$HIVEUSER’@’%’ IDENTIFIED BY ‘$HIVEPASSWORD’; mysql> GRANT ALL PRIVILEGES ON *.* TO ‘$HIVEUSER’@’%’; mysql> flush privileges;
Where
$HIVEUSER
is the Hive user name and$HIVEPASSWORD
is the Hive user password.
For Oracle only: Load the Hive Metastore Schema
The Hive Metastore database schema must be pre-loaded into your Oracle database using the schema script:
sqlplus $HIVEUSER/$HIVEPASSWORD < hive-schema-0.10.0.oracle.sql
The file
hive-schema-0.10.0.oracle.sql
is found in the/var/lib/ambari-server/resources/
directory of the Ambari Server machine, once you have completed the Set Up the Bits step in the install process.
