Better error messages regarding partitions and union all?
---------------------------------------------------------
Key: HIVE-825
URL: https://issues.apache.org/jira/browse/HIVE-825
Project: Hadoop Hive
Issue Type: Improvement
Reporter: Adam Kramer
I'm having trouble debugging a pretty complicated query. I see this two
messages currently, which I can fix after a bunch of debugging...but I would
like to suggest some possible changes to the errors.
FAILED: Error in semantic analysis: The query does not reference any valid
partition. To run this query, set hive.mapred.mode=nonstrict
...it would be awesome if you could tell me what table (real name and/ or
alias, and/or the line where it was first referenced) is lacking the partition
query. I'm almost certain that this is because my ds='foo' requirement is in
an ON clause and not a WHERE clause, but I don't want to set nonstrict in the
general case because it scares me.
Also:
FAILED: Error in semantic analysis: Schema of both sides of union should
match: source:_col0 source
...it would similarly be awesome if it could tell me what "source:_col0"
means, how the sides of the union do not match, why they don't match, or what
doesn't match.
