Description
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.
