-------------------------------
Summary: Better error message and error code for HoS exceptions
Key: HIVE-18283
URL: https://issues.apache.org/jira/browse/HIVE-18283
Project: Hive
Issue Type: Improvement
Components: Spark
Reporter: Chao Sun
Assignee: Chao Sun
Right now HoS only use a few error codes. For the majority of the errors, user
will see an error code 1 followed by a lengthy stacktrace. This is not ideal
since:
1. It is often hard to find the root cause - sometimes it is hidden deeply
inside the stacktrace.
2. After identifying the root cause, it is not easy to find a fix. Often user
have to copy & paste the error message and google them.
3. It is not clear whether the error is transient or not, depending on which
user may want to retry the query.
To improve the above, this JIRA propose to assign error code & canonical error
messages for different HoS errors. We can take advantage of the existing
{{ErrorMsg}} class.
