> Key: GEODE-1617
> URL: https://issues.apache.org/jira/browse/GEODE-1617
> Project: Geode
> Issue Type: Bug
> Components: gfsh
> Affects Versions: 1.0.0-incubating.M2
> Reporter: Kevin Duling
> Assignee: Kevin Duling
> Fix For: 1.0.0-incubating
>
>
> Per this
> [thread|https://www.mail-archive.com/dev@geode.incubator.apache.org/msg04046.html],
> and this
> [thread|https://www.mail-archive.com/dev@geode.incubator.apache.org/msg07079.html]
> on the dev forums and [geode
> documentation|http://docs-geode-develop.cfapps.io/docs/basic_config/data_regions/region_naming.html],
> region names may only consist of alphanumeric characters, an underscore, and
> a hyphen. These rules are not enforced.
> E.g., it is possible to create a region with:
> {{gfsh> create region --name=not^good --type=REPLICATE}}
> Some of these regions may be removed with the {{destroy}} command, while
> others cannot be located.
