Subject [jira] [Updated] (AMBARI-1426) Create cluster level Custom Action support
Date Tue, 17 Sep 2013 17:24:57 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-1426?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sumit Mohanty updated AMBARI-1426:
----------------------------------

    Description: 
While managing an HDP cluster, the admin may need to execute custom scripts etc. to perform
house-keeping operations. Ambari support for smoke test can be viewed as one such operation,
which has a first class support in Ambari. It is conceivable that in future releases several
such operations need to be supported by Ambari. Some such requirements are:
* Validate Kerberos settings
* Perform metadata check/backup (e.g. fsck) prior to upgrade
* Dump the list of datanodes

Rather than designing each of these capabilities in a one-off fashion, it is useful to develop
an infrastructure to execute such operations and then define new operations based on the infrastructure.



  was:
* API changes for action definition
* API changes to manage action results
* DB changes for action definition and results
** Query support to get past results
* Python template for actions
* Server side support for creating an action
** POST handler for an action
** Validate the action parameters
** Create stage/task plan
** Return request/action id
* Server side support for managing an action
** Monitor for action queue (enhance the request monitor)
** Evaluate host specific action results and update over-all action summary
** Handle timeouts
* Agent support for executing an action
** Python script runner
** Provide default context
** Provide supplied inputs
** Reporting back the result and progress
* Logging recommendations for custom actions
* Modify setup to deploy custom-actions
