Zheng Shao commented on HIVE-1100:
----------------------------------
What will be the semantics of pre-execution and post-execution hooks?
Shall we re-execute pre-execution hooks every time we resume the job?
Shall we fail the query if the post-execution hooks failed?
My preference is to treat the hooks as a task in the query plan - once it
succeeds then we don't run it again when resuming the query.
> Make it possible for users to retry map-reduce jobs in a single Hive query

> Project: Hadoop Hive
> Issue Type: New Feature
> Affects Versions: 0.6.0

> Sometimes a single hive query get compiled into several map-reduce jobs, and

> We should allow the user to start from the point of failure to continue the
> query.
