These jobs can > be very large because of counters. It would be nice to have a pluggable > interface for the cacheing and querying of the cached data so that we can > play around with different implementations. Also just for cleanness of the > code it would be nice to split the very large JobHistoryServer.java into a > few smaller ones that are more understandable and readable. -- This message is automatically generated by JIRA.
