Jason Gauci created DRILL-8048:
----------------------------------
Summary: Ability to cast unsigned int to int & float
Key: DRILL-8048
URL: https://issues.apache.org/jira/browse/DRILL-8048
Project: Apache Drill
Issue Type: Improvement
Affects Versions: 1.19.0
Reporter: Jason Gauci
Loading a parquet file with an unsigned int64 and trying to group by that
column fails because the casts from unsigned int to int/float are not
implemented. Added uint casts to Casts.tdd fixes the issue.
Before:
{{apache drill> SELECT map_id FROM dfs.`...` group by map_id;}}
{{{}Error: INTERNAL_ERROR ERROR: Failure while materializing
expression.{}}}{{{}Errors:{}}}
{{Error in expression at index -1. Error: Missing function implementation:
[castFLOAT4(UINT8-OPTIONAL)]. Full expression: --UNKNOWN EXPRESSION--.}}
{{{}Fragment: 3:2{}}}{{{}Please, refer to logs for more
information.{}}}{{{}[Error Id: e521b4d4-3138-49d7-8284-58377af97238 on
localhost:31010] (state=,code=0){}}}
After, it works as expected.
