-------------------------------------
Component & AM log from error case attached
> Component name with character dash ( "-" ) in it errors out
> -----------------------------------------------------------
>
> Key: SLIDER-1070
> URL: https://issues.apache.org/jira/browse/SLIDER-1070
> Project: Slider
> Issue Type: Bug
> Components: core
> Affects Versions: Slider 0.80
> Reporter: Manoj Samel
> Attachments: am.log, component_agent.log
>
>
> Slider version 0.80 with secured cluster.
> Attempt to create a component with characters like dash '-' or many other
> characters fail to bring up the component with error. It seems the only valid
> character in component name besides [A-Z][a-z[0-9] is underscore '_'.
> Per discussion, dash is a allowed character and should work, hence filing
> jira.
> I recreated issue with OOB jmemcached by creating component name my-name.
> The component fails to come up. The component agent log shows following
> error.
