Oozie Quick Start

These instructions install and run Oozie using an embedded Tomcat server and an embedded Derby database.

For detailed install and configuration instructions refer to Oozie Install .

System Requirements

  • Unix (tested in Linux and Mac OS X)
  • Java 1.6+
  • Hadoop
  • ExtJS library (optional, to enable Oozie webconsole)

The Java 1.6+ bin directory should be in the command path.

Server Installation

IMPORTANT: Oozie ignores any set value for OOZIE_HOME , Oozie computes its home automatically.

  • Download or build an Oozie binary distribution
  • Download a Hadoop binary distribution
  • Download ExtJS library (it must be version 2.2)

NOTE: The ExtJS library is not bundled with Oozie because it uses a different license.

NOTE: It is recommended to use a Oozie Unix user for the Oozie server.

Expand the Oozie distribution tar.gz .

Expand the Hadoop distribution tar.gz (as the Oozie Unix user).

NOTE: Configure the Hadoop cluster with proxyuser for the Oozie process.

The following two properties are required in Hadoop core-site.xml:

  <!-- OOZIE -->

Replace the capital letter sections with specific values and then restart Hadoop.

Expand the Oozie hadooplibs tar.gz in the same location Oozie distribution tar.gz was expanded. A *hadooplibs/* directory will be created containing the Hadoop JARs for the versions of Hadoop that the Oozie distribution supports.

The ExtJS library is optional (only required for the Oozie web-console to work)

IMPORTANT: all Oozie server scripts (=oozie-setup.sh=, oozie-start.sh , oozie-run.sh and oozie-stop.sh ) run only under the Unix user that owns the Oozie installation directory, if necessary use sudo -u OOZIE_USER when invoking the scripts.

Create a libext/ directory in the directory where Oozie was expanded.

If using a version of Hadoop bundled in Oozie hadooplibs/ , copy the corresponding Hadoop JARs from hadooplibs/ to the libext/ directory. If using a different version of Hadoop, copy the required Hadoop JARs from such version in the libext/ directory.

If using the ExtJS library copy the ZIP file to the libext/ directory.

Run the oozie-setup.sh script to configure Oozie with all the components added to the libext/ directory.

$ bin/oozie-setup.sh

Create the Oozie DB using the 'ooziedb.sh' command line tool:

$ bin/ooziedb.sh create -sqlfile oozie.sql -runValidate DB Connection.
Check DB schema does not exist
Check OOZIE_SYS table does not exist
Create SQL schema
Create OOZIE_SYS table
Oozie DB has been created for Oozie version '3.2.0'

Start Oozie as a daemon process run:

$ bin/oozie-start.sh

To start Oozie as a foreground process run:

$ bin/oozie-run.sh

Check the Oozie log file logs/oozie.log to ensure Oozie started properly.

Using the Oozie command line tool check the status of Oozie:

$ bin/oozie admin -oozie http://localhost:11000/oozie -status

Using a browser go to the Oozie web console , Oozie status should be NORMAL .

Refer to the Running the Examples document for details on running the examples.

Client Installation

Copy and expand the oozie-client TAR.GZ file bundled with the distribution. Add the bin/ directory to the PATH .

Refer to the Command Line Interface Utilities document for a a full reference of the oozie command line tool.

NOTE: The Oozie server installation includes the Oozie client. The Oozie client should be installed in remote machines only.

Oozie Share Lib Installation

Expand the oozie-sharelib TAR.GZ file bundled with the distribution.

The share/ directory must be copied to the Oozie HOME directory in HDFS:

$ hadoop fs -put share share

IMPORTANT: This must be done using the Oozie Hadoop (HDFS) user. If a share directory already exists in HDFS, it must be deleted before copying it again.
