>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-agent, ambari-server
>    Affects Versions: 2.1.0
>            Reporter: Sumit Mohanty
>            Assignee: Sumit Mohanty
>             Fix For: 2.1.0

> Proposal:
> Introduce three config parameters in {{cluster-env}}
> * command_retry_enabled
> * command_retry_max_time_in_sec
> * commands_to_retry
> *command_retry_enabled* - true or false (default is false)
> *command_retry_max_time_in_sec* - how long to retry before giving up, default 0, which allows one try
> *commands_to_retry* - which commands are eligible for retry, if not set or empty then all commands are eligible, default "START"
> By default, retry for service check and custom commands (DECOMMISSION, RESTART, etc) are skipped
> As part of this change. properties from ambari.properties file will be removed. So only way to enable is to to provide configs in type cluster-env. So technically it can be disabled/enabled without restarting Ambari.
