[jira] [Created] (SPARK-45652) SPJ: Handle empty input partitions after dynamic filtering
Chao Sun created SPARK-45652:
--------------------------------
Summary: SPJ: Handle empty input partitions after dynamic filtering
Key: SPARK-45652
URL: https://issues.apache.org/jira/browse/SPARK-45652
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.4.1
Reporter: Chao Sun
When the number of input partitions become 0 after dynamic filtering, in {{BatchScanExec}}, currently SPJ will fail with error:
{code}
java.util.NoSuchElementException: None.get

{code}
This is because {{groupPartitions}} will return {{None}} for this case.
