             Summary: Adding support for MissingFiles when spark.sql.parquet.mergeSchema=true
                 Key: SPARK-43269
                 URL: https://issues.apache.org/jira/browse/SPARK-43269
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 3.4.0
            Reporter: Neil Jonkers


Hello,

With `spark.sql.files.ignoreMissingFiles=true` we notice [readParquetFootersInParallel|[https://github.com/apache/spark/blob/52c1068190803d856959ba563642a3e440cc086c/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetFileFormat.scala#L438]] can still encounter `FileNotFoundException`. 

I notice function `readParquetFootersInParallel` can handle scenario where `{{{}spark.sql.files.ignoreCorruptFiles=true`.{}}}

 

Would it be feasible to support the scenario where `spark.sql.files.ignoreMissingFiles=true` when `readParquetFootersInParallel` is called?

 

Thank you
