---------------------------------------------
Summary: "SELECT * BadAlias ..." yields "SYSTEM ERROR ... index
(-1) must not be negative"
Key: DRILL-2956
URL: https://issues.apache.org/jira/browse/DRILL-2956
Project: Apache Drill
Issue Type: Bug
Reporter: Daniel Barclay (Drill)
Issuing the query:
select * alias from `dfs.tmp`.`empty_file.json` ;
(where /tmp/empty_file.json exists and is completely empty) yields an internal
error:
> select * alias from `dfs.tmp`.`empty_file.json` ;
Error: SYSTEM ERROR: Unexpected exception during fragment initialization: index
(-1) must not be negative

It doesn't seem to matter whether the input file is empty or contains some
JSON.
(Using a table from INFORMATION_SCHEMA (a schema whose tables and columns are
known statically) does not yield the same error:
> select * alias from INFORMATION_SCHEMA.CATALOGS;

However, that error doesn't seem right either. (I would think that trying to
give an alias name after "*" would be a syntax error (rather than a name lookup
error).))
