def validateMetadata(): Option[String] = {
if (format != ParquetReadFormat || rootPaths.isEmpty) {
// Only Parquet is needed for metadata validation so far.
return None
}
val fileLimit = GlutenConfig.get.parquetMetadataFallbackFileLimit
.max(GlutenConfig.get.parquetEncryptionValidationFileLimit)
val parquetOptions = new
ParquetOptions(CaseInsensitiveMap(properties), SQLConf.get)
val parquetMetadataValidationResult =
ParquetMetadataUtils.validateMetadata(
format,
rootPaths,
hadoopConf,
parquetOptions,
fileLimit)
parquetMetadataValidationResult.map(
reason => s"Detected unsupported metadata in parquet files: $reason")
}
```
The issue still exists, the rootPaths maybe huge in large partition table,
too many list call happens..
