Virag Kothari resolved OOZIE-781.
---------------------------------
Resolution: Fixed
> Xerces validator used by Java gets stuck during pattern matching
> ----------------------------------------------------------------
>
> Key: OOZIE-781
> URL: https://issues.apache.org/jira/browse/OOZIE-781
> Project: Oozie
> Issue Type: Bug
> Reporter: Virag Kothari
>
> The regex validator tries to validate the 'workflow-app name' against the
> pattern
> <xs:pattern value="([a-zA-Z_]([\-_a-zA-Z0-9])*){1,39})"/>. If the 'name' is
> very long and doesn't match against the pattern used in schema, it gets stuck
> for a
> long time and heavily increases the CPU usage.
> Specifically the users saw this when they used a period in their wf name
> This problem is solved in xerces 2.10.
