Karthik Amarnath updated HDFS-15168:
------------------------------------
Description: 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]|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 Linux identity to verify if the file owner is the same as Linux
identity, but the underlying ABFS driver returns the AAD identity. Hence need
ABFS driver enhancement.
