> Hive uses 'distcp' to copy files in parallel between HDFS encryption zones when the {{hive.exec.copyfile.maxsize}} threshold is lower than the file to copy. This 'distcp' is also executed when copying to S3, but it is causing slower copies.
> We should not invoke distcp when copying to blobstore systems.
