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
