             Summary: MAX_NODE_NAME_LEN is too small for auto generated action names
                 Key: OOZIE-2025
                 URL: https://issues.apache.org/jira/browse/OOZIE-2025
             Project: Oozie
          Issue Type: Bug
            Reporter: Burak Gursoy
            Priority: Minor


Hi,

There is a limitation on action name lengths and the limit for that is too low:

private static final int MAX_NODE_NAME_LEN = 50; // [1]

You can easily hit that limit if the action names are auto generated and a bit verbose to have them meaningful names (for visual checking/debugging the resulting workflow.xml).

There are two workarounds:

i) hash the generated names (will make them obscure for human eyes)

ii) substring the actual name until 35-40 chars and append a random string for the remaining 10 chars (that's what we're doing-- but still not very convenient)

The limit can still be there but it will be really nice to have either:

- Increase to something like 200 -- or even higher
- The limit can be converted into an overridable configuration section, which will solve the problem completely for the users.

Thanks,
Burak
