------------------------------------
Summary: Add a way to differentiate between hooks that
should/should not fail a query
Key: HIVE-3169
URL: https://issues.apache.org/jira/browse/HIVE-3169
Project: Hive
Issue Type: Bug
Components: Query Processor
Reporter: Santhosh Raman
Right now, if any hook fails the query fails. In particular if a post hook
fails, even if the query itself succeeded, it will fail because of this.
In some cases, this may be desired behavior, e.g. if the Replication Hook fails
the output will not be replicated (there are arguments for and against this but
that is probably best left for a separated discussion).
However, if something like the sample concurrency hook fails, we could just
leave concurrency untouched, display a warning to the user (to hopefully either
provoke a Hive Users post from the user or at least have it show up in the log
monitor), and continue the query.
We need to add a way to differentiate between these hooks and to add that error
handling.
