-------------------------------------
Summary: OrcColumnarBatchReader uncaught exception
Key: SPARK-34594
URL: https://issues.apache.org/jira/browse/SPARK-34594
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.4.5
Reporter: Zhang Jianguo
RecordReaderInterator#hasNext doesn't handle exception thrown from
OrcColumnarBatchReader#nextKeyValue
```scala
override def hasNext: Boolean = {
if (!finished && !havePair) {
finished = !rowReader.nextKeyValue // Exception thrown from here
if (finished) {
// Close and release the reader here; close() will also be called when
the task
// completes, but for tasks that read from many files, it helps to
release the
// resources early.
close()
}
havePair = !finished
}
!finished
}
```
