> {{hadoop fs -put}} currently supports the {{-p}} option. When used, this
> option preserves the source file's access time, modification time, ownership
> and mode. If the destination is HDFS, then this effectively means HDFS must
> be configured to use modification time. If the HDFS deployment chooses to
> disable access time by setting {{dfs.namenode.accesstime.precision}} to 0,
> then attempts to use the {{-p}} flag all fail with "Access time for hdfs is
> not configured." This issue proposes to introduce separate options for
> preserving just ownership, just mode, or just times. For backwards
> compatibility, the behavior of a bare {{-p}} must continue to be preserving
> all 3.
