Subject [jira] [Commented] (HIVE-2038) Metastore listener
Date Fri, 22 Apr 2011 18:23:05 GMT


Carl Steinbach commented on HIVE-2038:

I think the meaning of "finalizing" a partition is actually defined by the metastore client,
since it's the client that has to call finalizePartition(). But when is the client supposed
to call this? What happens if you have multiple listeners registered which each has a different
idea of what it means to finalize a partition? I think the main problem with this is that
the name of the method gives the impression that this is somehow well defined, when in fact
the definition is left completely up to the application.

It sounds like what you actually want is a mechanism that allows the metastore client to send
application specific events to metastore listeners. Is this accurate?
