-----------------------------------
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
