This documentation is intended to provide instructions on how to run Stratosphere locally on a single machine.
Go to the downloads page and get the ready to run package. If you want to interact with Hadoop (e.g. HDFS or HBase), make sure to pick the Stratosphere package matching your Hadoop version. When in doubt or you plan to just work with the local file system pick the package for Hadoop 1.2.x.
Stratosphere runs on all UNIX-like environments, e.g. Linux, Mac OS X, and Cygwin (for Windows). The only requirement for a local setup is Java 1.6.x or higher.
You can check the correct installation of Java by issuing the following command:
java -version
The command should output something comparable to the following:
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode)
For local mode Stratosphere is ready to go out of the box and you don't need to change the default configuration.
The out of the box configuration will use your default Java installation. You can manually set the environment variable JAVA_HOME or the configuration key env.java.home in conf/stratosphere-conf.yaml if you want to manually override the Java runtime to use. Consult the configuration page for further details about configuring Stratosphere.
You are now ready to start Stratosphere. Unpack the downloaded archive and change to the newly created stratosphere directory. There you can start Stratosphere in local mode:
$ tar xzf stratosphere-*.tgz
$ cd stratosphere
$ bin/start-local.sh
Starting Nephele job manager
You can check that the system is running by checking the log files in the logs directory:
$ tail log/nephele-*-jobmanager-*.log
INFO ... - Initializing memory manager with 409 megabytes of memory
INFO ... - Trying to load eu.stratosphere.nephele.jobmanager.scheduler.local.LocalScheduler as scheduler
INFO ... - Setting up web info server, using web-root directory ...
INFO ... - Web info server will display information about nephele job-manager on localhost, port 8081.
INFO ... - Starting web info server for JobManager on port 8081
The JobManager will also start a web frontend on port 8081, which you can check with your browser at http://localhost:8081.
