> Hive does not return meaningful error messages for runtime errors. Also, the
> same error code is returned for a whole bunch of unrelated errors. A
> programmatic caller cannot decide if it should retry or give up. This JIRA
> will get the ball rolling for having Hive return useful error codes and
> display useful messages when something goes wrong. I propose the following
> partitioning of error codes:
> 10000 to 19999: Errors that occur during semantic analysis and compilation of
> the query. Hive already does a pretty good job for these. Error codes will be
> attached to the error messages currently being used.
> 20000 to 29999: Runtime errors where Hive believes that retries will not
> succeed and the caller should not bother retrying.
> 30000 to 39999: Runtime errors which Hive thinks are probably transient and
> retrying may succeed.
> 40000 to 49999: Runtime errors where Hive is unable to say anything about
> whether retries will succeed or not. Ideally, we want to avoid using this
> range as much as possible.
> Once we have this in place, over time we can migrate errors occurring in Hive
> operators to use this scheme. This patch will deal with setting up the error
> code space, setting up the mechanism for failed MapReduce tasks to relay the
> error code back to Hive client, and using this new scheme for a couple of
> common errors.
