Manoj Samel created SLIDER-1070:
-----------------------------------
Summary: 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
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.
