        "description": "Sends event if the yarn-cluster is empty/free to trigger other stuff (e.g. send you an email or start another application)\n\nThe HadoopYarnClusterChecker-Class checks your cluster if there is any application run on it. In case your cluster is free it fires an event.\n\n# how it works:\n* it's false positive: if there is any error like it can not connect to your yarn-rest-api it sends the event.\n* algorithm:\n  * receive data from: \"/ws/v1/cluster/apps\"-REST endpoint\n  * are there applications with the state \"running\"?\n    * Yes: Is this application excluded?\n    * Yes: Are there more running applications?\n      * No: send the event\n      * Yes: sleep for the intervall & start with the first bulletin-point\n# Excludes\n* has to be a String\n* excludes for state-attribute are forbidden!\n* don't forget to escape the \\\"\n* JSON-Notation:\n  * Array\n  * Key-Value-Object\n  * Key: XML-Tag from the Yarn-Api\n  * example: \n  ```json\n  \"[\n  {\\\"name\\\":\\\"Zeppelin\\\"},\n  {\\\"name\\\":\\\"Zeppelin1\\\"}\n  ]\"\n  ```\n    * meaning: all Applications with the Name \"Zeppelin\" and \"Zeppelin1\" will be excluded in case they're running\n    * filtering:\n      * for state-attribute is forbidden!\n      * for multiple attributes like an AND should work:\n        ```json\n        [\n         {\n          \"name\":\"Zeppelin\", \n          \"priority\":0\n          }\n        ]\n        ```\n\n# How to use it:\n\n```python\nimport hadoop-yarn-cluster-checker-lib\n\nchecker = HadoopYarnClusterChecker(server=args.server, path=args.path, intervall=args.intervall, log=args.log,\n                                                               excludes=args.excludes)\nchecker.on_empty_cluster += event_empty\n```\n\n# Donations\n[![paypal](https://www.paypalobjects.com/en_US/DK/i/btn/btn_donateCC_LG.gif)](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=EN22Z95HKGD74&source=url) \n\n# Cheatsheet for me\nlore ipsem\n## Twine\nonly works with: twine upload --repository-url https://test.pypi.org/legacy/ dist/*",
