> ABFS driver does not support the translation of AAD Service principal (SPI) to Linux identities causing metadata operation failure. Hadoop MapReduce client [[JobSubmissionFiles|https://github.com/apache/hadoop/blob/d842dfffa53c8b565f3d65af44ccd7e1cc706733/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/JobSubmissionFiles.java#L138]] expects the file owner permission to be the Linux identity, but the underlying ABFS driver returns the AAD Object identity. Hence need ABFS driver enhancement.
