[jira] [Commented] (OOZIE-2025) MAX_NODE_NAME_LEN is too small for auto generated action names

["David Morel (JIRA)" <ji...@apache.org>]

David Morel commented on OOZIE-2025:
------------------------------------

Is there any reason for this limitation? In the MySQL backend, all the names have a datatype of VARCHAR(255). If we patch the ParamChecker class, can we expect it to Just Work(tm)?

> 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.
> Also I think such limits need to be checked with the `oozie validate` command as well as such xmls shouldn't pass as valid if there is a limitation.
> Thanks,
> Burak
