[jira] [Updated] (SPARK-43269) Adding support for MissingFiles when spark.sql.parquet.mergeSchema=true

     [ https://issues.apache.org/jira/browse/SPARK-43269?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Neil Jonkers updated SPARK-43269:
---------------------------------
    Description: 
Hello,

With`spark.sql.files.ignoreMissingFiles=true` we notice [readParquetFootersInParallel|#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
