It also works with your own Hadoop cluster. Some important features: * Run jobs on EMR, your own Hadoop cluster, or locally (for testing). * Write multi-step jobs (one map-reduce step feeds into the next) * Duplicate your production environment inside Hadoop * Upload your source tree and put it in your job's $PYTHONPATH * Run make and other setup scripts * Set environment variables (e.g. $TZ) * Easily install python packages from tarballs (EMR only) * Setup handled transparently by mrjob.conf config file * Automatically interpret error logs from EMR * SSH tunnel to hadoop job tracker on EMR * Minimal setup * To run on EMR, set $AWS_ACCESS_KEY_ID and $AWS_SECRET_ACCESS_KEY * To run on your Hadoop cluster, install simplejson and make sure $HADOOP_HOME is set. More info: * Install mrjob: python setup.py install * Documentation: http://packages.python.org/mrjob/ * PyPI: http://pypi.python.org/pypi/mrjob * Discussion: http://groups.google.com/group/mrjob * Development is hosted at github: http://github.com/Yelp/mrjob What's new? ------------------- v0.2.5, 2011-04-29 -- Hadoop input and output formats * Added hadoop_input/output_format options * You can now specify a custom Hadoop streaming jar (hadoop_streaming_jar) * extra args to hadoop now come before -mapper/-reducer on EMR, so that e.g. -libjar will work (worked in hadoop mode since v0.2.2) * hadoop mode now supports s3n:// URIs (Issue #53)
