URL: https://github.com/apache/iceberg/issues/3703
` Column joinCond = nameEqual.and(actualContains);
List<String> orphanFiles = actualFileDF.join(validFileDF, joinCond,
"leftanti")
.as(Encoders.STRING())
.collectAsList();
Tasks.foreach(orphanFiles)
.noRetry()
.suppressFailureWhenFinished()
.onFailure((file, exc) -> LOG.warn("Failed to delete file: {}",
file, exc))
.run(deleteFunc::accept);`
spark all path collect to driver，When there are too many files，outofmemory
，It doesn't make sense， Deletion should be performed directly on the cluster
rather than being collected to the driver for deletion，I can't carry it out now
