> A prior ticket (see https://issues.apache.org/jira/browse/SPARK-44081) implemented a simplification to the PartitionedFileUtils API that removed redundant `path` arguments, which can be obtained directly from the `FileStatusWithMetadata` object. To avoid repeatedly having to compute the path, this change changed `FileStatusWithMetadata.getPath` from a def to a lazy val. However, this increases the memory requirements as the path now needs to be kept in memory throughout the lifetime of a `FileStatusWithMetadata` object. This can lead to OOMs so we should revert this change and make `getPath` to be a `def`.
