Review request for oozie, András Piros and Attila Sasvari.
Repository: oozie-git
Description
-------
Upon SLACalculatorMemory.addRegistration, Oozie puts an entry into an in-memory
concurrent hashmap ("slaMap"), and later persists it in the Oozie database.
However, if there is a failure during the database operation, a
JPAExecutorException is thrown, and the entry is not removed from the SLA map.
It may introduce inconsistency between the Oozie database and the SLA map.
To prevent this, a rollback mechanism (with proper logging) should be
implemented. It would also make sense to do more sanity/consistency check in
the Oozie server.
