----------------------------------
Summary: Need better error messages when convert_to is given a bad
type
Key: DRILL-3544
URL: https://issues.apache.org/jira/browse/DRILL-3544
Project: Apache Drill
Issue Type: Bug
Reporter: Ted Dunning
The first query below fails because I used UTF-8 instead of UTF8. This should
have a decent error message.
{code}
0: jdbc:drill:zk=local> SELECT CONVERT_TO('[ [1, 2], [3, 4], [5]]' ,'UTF-8') AS
MYCOL1 FROM sys.version;
Error: SYSTEM ERROR: org.apache.drill.exec.work.foreman.ForemanException:
