------------------------------------

             Summary: Make Utils.chmod700 atomic on POSIX FS
                 Key: SPARK-59756
                 URL: https://issues.apache.org/jira/browse/SPARK-59756
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 4.4.0
            Reporter: Holden Karau


Utils.chmod700 runs a number of setReadable/setWritable/... (in total 6 because 
it manually sets once for others and once for owner). When running on a POSIX 
FS we can just do this as one atomic call.
