This work was originally derived from the Cloudera CDH Cloud Scripts for managing Hadoop in Amazon EC2 (https://wiki.cloudera.com/display/DOC/CDH+Cloud+Scripts). We needed a way to manage Hadoop, Cassandra, and other distributed services, thus PyStratus was born. Thanks to Cloudera for providing a great starting point for us!Currently only Amazon EC2 is supported, but we hope to add new cloud providers very soon.
To get up and running quickly, use virtualenv and install PyStratus with these instructions:
$ mkvirtualenv stratus
(stratus)$ pip install https://github.com/digitalreasoning/PyStratus/archive/master.zip
...
# issue commands like:
(stratus)$ stratus list
(stratus)$ stratus exec HADOOP_CLUSTER launch-cluster 3
(stratus)$ stratus exec HADOOP_CLUSTER terminate-cluster
...
(stratus)$ deactivate # to leave virtualenv
Additionally, the following script is sufficient (assumes that you have a ~/bin directory and it is on your PATH):
INSTALL_DIR=~/Tools/pystratus
virtualenv $INSTALL_DIR --no-site-packages
$INSTALL_DIR/bin/pip install https://github.com/digitalreasoning/PyStratus/archive/master.zip
ln -snf $INSTALL_DIR/bin/stratus ~/bin/stratus
PyStratus uses the following dependencies:
- Python 2.5+
- boto
- simplejson
- prettytable
- setuptools
- dateutil
- PyYAML
- cElementTree or elementree
- Fabric
You may also check out the project and run "python setup.py install" and the command "stratus" will now available and an egg file will be located in your site-packages directory. You may want to run the command with sudo to install it for all users.
