Khurram Faraaz commented on DRILL-3583:
---------------------------------------

Verified on master commit ID: b525692e
We now get a better error message.

{code}
0: jdbc:drill:schema=dfs.tmp> select sum(full_name) from cp.`employee.json`;
Error: UNSUPPORTED_OPERATION ERROR: Only COUNT, MIN and MAX aggregate functions supported
for VarChar type

> With the implementation of DRILL-3319, a bug was introduced whereby the codegen for an
aggregate when SUMing a varchar column fails:
> {code}
> 0: jdbc:drill:zk=local> select sum(full_name) from cp.`employee.json`;
> java.lang.RuntimeException: java.sql.SQLException: SYSTEM ERROR: CompileException: Line
57, Column 177: Unknown variable or type "logger"
> Fragment 0:0

>         at sqlline.TableOutputFormat$ResizingRowsProvider.next(TableOutputFormat.java:87)
>         at sqlline.TableOutputFormat.print(TableOutputFormat.java:118)

>         at sqlline.SqlLine.start(SqlLine.java:366)
>         at sqlline.SqlLine.main(SqlLine.java:259)
> {code}
> This is due to the fact AggregateErrorFunctions now builds its errors with a "logger"
static field, which does not exist in the codegenned code.
> We either need to include a static logger in codegen aggregates, or revert back to simpler
exceptions for these functions.
