----------------------------------------
Summary: Incorrect pattern regex for IDENTIFIER
Key: OOZIE-1999
URL: https://issues.apache.org/jira/browse/OOZIE-1999
Project: Oozie
Issue Type: Bug
Components: coordinator
Reporter: Jozsef Szekrenyes
Priority: Minor
The pattern value for IDENTIFIER in the oozie xml-schema is :
"([a-zA-Z_]([\-_a-zA-Z0-9])*){1,39}"
(see
http://oozie.apache.org/docs/4.0.0/WorkflowFunctionalSpec.html#Oozie_Schema_Version_0.5)
It seems the idea was to limit the length of an identifier to 40 characters.
Because of the '*', the limitation doesn't have any effect - strings with
arbitrary length will match the pattern. This caused issues like OOZIE-781.
In order the limit on length to be effective, the '*' should be removed, so the
pattern should be:
"([a-zA-Z_]([\-_a-zA-Z0-9])){1,39}"
