>
> Key: ASTERIXDB-2757
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2757
> Project: Apache AsterixDB
> Issue Type: Improvement
> Components: EXT - External data
> Affects Versions: 0.9.5
> Reporter: Hussain Towaileb
> Assignee: Hussain Towaileb
> Priority: Major
> Fix For: 0.9.5
>
>
> In some case, for example, providing a pattern such as *{{[a-b0-9.}}**
> without properly closing the bracket, would result in a failure that the
> provided pattern is invalid. However, this is a valid pattern, in the above
> case, the open (unclosed) bracket should be escaped as this is a literal and
> not a character class case.
>
> Such cases should be handled properly, as the above could be a valid file
> name that is *{{[a-b0-9.json}}* for example.
