Building Oozie

Download a source distribution of Oozie from the "Releases" drop down menu on the Oozie site .

Expand the source distribution tar.gz and change directories into it.

The simplest way to build Oozie is to run the mkdistro.sh script:

$ bin/mkdistro.sh [-DskipTests]Running =mkdistro.sh= will create the binary distribution of Oozie. By default, oozie war will not contain hadoop and
hcatalog libraries, however they are required for oozie to work. There are 2 options to add these libraries:
1. At install time, copy the hadoop and hcatalog libraries to libext and run oozie-setup.sh to setup oozie war. This is
suitable when same oozie package needs to be used in multiple set-ups with different hadoop/hcatalog versions.
2. Build with -Puber which will bundle the required libraries in the oozie war. Further, the following options are
available to customise the versions of the dependencies:
-P<profile> - default hadoop-2. Valid are hadoop-1, hadoop-2 or hadoop-3. Choose the correct hadoop
profile depending on the hadoop version used.
-Dhadoop.version=<version> - default 1.2.1 for hadoop-1, 2.4.0 for hadoop-2 and 3.0.0-SNAPSHOT for hadoop-3
-Dhadoop.auth.version=<version> - defaults to hadoop version
-Ddistcp.version=<version> - defaults to hadoop version
-Dpig.version=<version> - default 0.16.0
-Dpig.classifier=<classifier> - default none
-Dsqoop.version=<version> - default 1.4.3
-Dsqoop.classifier=<classifier> - default hadoop100
-Dtomcat.version=<version> - default 6.0.53
-Dopenjpa.version=<version> - default 2.2.2
-Dxerces.version=<version> - default 2.10.0
-Dcurator.version=<version> - default 2.5.0
-Dhive.version=<version> - default 0.13.1 for hadoop-1, 1.2.0 for hadoop-2 and hadoop-3 profile
-Dhbase.version=<version> - default 0.94.2

More details on building Oozie can be found on the Building Oozie page.

System Requirements

• Unix (tested in Linux and Mac OS X)
• Java 1.7+
• Hadoop
  • Apache Hadoop (tested with 1.2.1 & 2.4.0+)
• ExtJS library (optional, to enable Oozie webconsole)
  • ExtJS 2.2

The Java 1.7+ bin directory should be in the command path.

Server Installation

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

• 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: Oozie UI browser compatibility Chrome (all), Firefox (3.5), Internet Explorer (8.0), Opera (10.5).

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 -->
  <property>
    <name>hadoop.proxyuser.[OOZIE_SERVER_USER].hosts</name>
    <value>[OOZIE_SERVER_HOSTNAME]</value>
  </property>
  <property>
    <name>hadoop.proxyuser.[OOZIE_SERVER_USER].groups</name>
    <value>[USER_GROUPS_THAT_ALLOW_IMPERSONATION]</value>
  </property>

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

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

IMPORTANT: all Oozie server scripts (=oozie-setup.sh=, oozied.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.

As of Oozie 3.3.2, use of oozie-start.sh , oozie-run.sh , and oozie-stop.sh has been deprecated and will print a warning. The oozied.sh script should be used instead; passing it start , run , or stop as an argument will perform the behaviors of oozie-start.sh , oozie-run.sh , and oozie-stop.sh respectively.

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

If using the ExtJS library copy the ZIP file to the libext/ directory. If hadoop and hcatalog libraries are not already included in the war, add the corresponding libraries to libext/ directory.

A "sharelib create -fs fs_default_name [-locallib sharelib]" command is available when running oozie-setup.sh for uploading new sharelib into hdfs where the first argument is the default fs name and the second argument is the Oozie sharelib to install, it can be a tarball or the expanded version of it. If the second argument is omitted, the Oozie sharelib tarball from the Oozie installation directory will be used. Upgrade command is deprecated, one should use create command to create new version of sharelib. Sharelib files are copied to new lib_ directory. At start, server picks the sharelib from latest time-stamp directory. While starting server also purge sharelib directory which is older than sharelib retention days (defined as oozie.service.ShareLibService.temp.sharelib.retention.days and 7 days is default).

"prepare-war [-d directory]" command is for creating war files for oozie with an optional alternative directory other than libext.

db create|upgrade|postupgrade -run [-sqlfile ] command is for create, upgrade or postupgrade oozie db with an optional sql file

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

$ bin/oozie-setup.sh prepare-war [-d directory] [-secure]
                     sharelib create -fs <FS_URI> [-locallib <PATH>]
                     sharelib upgrade -fs <FS_URI> [-locallib <PATH>]
                     db create|upgrade|postupgrade -run [-sqlfile <FILE>]

The -secure option will configure Oozie to use HTTP (SSL); refer to Setting Up Oozie with HTTPS (SSL) for more details.

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

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

Start Oozie as a daemon process run:

$ bin/oozied.sh start

To start Oozie as a foreground process run:

$ bin/oozied.sh run

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.

System Requirements

• Unix (tested in Linux and Mac OS X)
• Java 1.7+

The Java 1.7+ bin directory should be in the command path.

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 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.
