Denes Bodo created OOZIE-3561:
---------------------------------
Summary: Forkjoin validation is slow when there are many actions
in chain
Key: OOZIE-3561
URL: https://issues.apache.org/jira/browse/OOZIE-3561
Project: Oozie
Issue Type: Bug
Components: core
Affects Versions: 5.1.0
Reporter: Denes Bodo
Assignee: Denes Bodo
In case we have a workflow which has, let's say, 80 actions after each other:
{{a1 -> a2 -> ... a80}}
then the validator code "never" finishes.
Currently the validation (in my understanding) does depth first checks from the
start node and runs in time of n! . This is confirmed as when we split this
huge workflow into two 40-element workflow then we get 2x ~40!-step in
validation instead of ~80! steps.
Guys, could you please confirm or disprove my theory?
Thanks
