Oozie db to PGSQL in Ambari install.

[#1]

While installing Ambari on CentOS7, i was asked about the Oozie db target. I opted to use PGSQL, but that failed, since i did not have any idea what the UserName, Pwd or DBName defaulted to or where to set them. The instructions page gives not idea what to use for them.

@Dave Woodruff I highly recommend using the search tool on Hortonworks Documentation page to find what you're looking for. Here's the doc that can help.

Hi, Please see this guide http://docs.hortonworks.com/HDPDocuments/Ambari-2.1.2.0/bk_ambari_reference_guide/content/_using_ooz...

Using Oozie with PostgreSQL

To set up PostgreSQL for use with Oozie:

1. On the Ambari Server host, stage the appropriate PostgreSQL connector for later deployment.
   1. Install the connector.

      RHEL/CentOS/Oracle Linux

      yum install postgresql-jdbc

      SLES

      zypper install -y postgresql-jdbc

      UBUNTU

      apt-get install -y postgresql-jdbc

      DEBIAN

      apt-get install -y postgresql-jdbc

   2. Confirm that .jar is in the Java share directory.

      ls /usr/share/java/postgresql-jdbc.jar

   3. Change the access mode of the .jar file to 644.

      chmod 644 /usr/share/java/postgresql-jdbc.jar

   4. Execute the following command:

      ambari-server setup --jdbc-db=postgres --jdbc-driver=/usr/share/java/postgresql-jdbc.jar

2. Create a user for Oozie and grant it permissions.
   • Using the PostgreSQL database admin utility:

     echo "CREATE DATABASE <OOZIEDATABASE>;" | psql -U postgres

     echo "CREATE USER <OOZIEUSER> WITH PASSWORD '<OOZIEPASSWORD>';" | psql -U postgres

     echo "GRANT ALL PRIVILEGES ON DATABASE <OOZIEDATABASE> TO <OOZIEUSER>;" | psql -U postgres

   • Where <OOZIEUSER> is the Oozie user name, <OOZIEPASSWORD> is the Oozie user password and <OOZIEDATABASE> is the Oozie database name.

This is not reqired anymore when deploying ?

oozie.service.JPAService.create.db.schema=true

@Peter Bartal I would follow the documentation.
