Igor Kabiljo created HIVE-3475:
----------------------------------
Summary: INLINE UDTF doesn't convert types properly
Key: HIVE-3475
URL: https://issues.apache.org/jira/browse/HIVE-3475
Project: Hive
Issue Type: Bug
Components: UDF
Affects Versions: 0.10.0
Reporter: Igor Kabiljo
Priority: Minor
I suppose the issue is in line:
this.forwardObj[i]=res.convertIfNecessary(rowList.get(i),
f.getFieldObjectInspector());
there is never reason for conversion, it should just be:
this.forwardObj[i]= rowList.get(i)
Caused by: java.lang.ClassCastException: org.apache.hadoop.io.LongWritable
cannot be cast to java.lang.Long
