> Key: AMBARI-2278
> URL: https://issues.apache.org/jira/browse/AMBARI-2278
> Project: Ambari
> Issue Type: Bug
> Components: controller
> Affects Versions: 1.2.4
> Reporter: Sumit Mohanty
> Fix For: 1.2.5
>
>
> Due to many reasons (e.g. prior installation/cleanup of Hadoop components)
> its possible that hosts may be in an inconsistent state (e.g. a Hadoop
> component is installed but some directories are missing). If its OK for the
> user to erase and install Hadoop components then Ambari should support it.
> The Ambari feature is to clean up the host before installing Hadoop
> components.
