> Values of trash configuration and trash emptier state in namenode log are displayed in
milliseconds (but it should be seconds). This is very confusing because it makes you feel
that Trash does not remove data or the meaning of configuration settings changed.
> {code}
> // org.apache.hadoop.fs.TrashPolicyDefault
>   @Override
>   public void initialize(Configuration conf, FileSystem fs, Path home) {
>     ...
>     this.deletionInterval = (long)(conf.getFloat(
>         FS_TRASH_INTERVAL_KEY, FS_TRASH_INTERVAL_DEFAULT)
>         * MSECS_PER_MINUTE);
>     this.emptierInterval = (long)(conf.getFloat(
>         FS_TRASH_CHECKPOINT_INTERVAL_KEY, FS_TRASH_CHECKPOINT_INTERVAL_DEFAULT)
>         * MSECS_PER_MINUTE);
>     LOG.info("Namenode trash configuration: Deletion interval = " +
>              this.deletionInterval + " minutes, Emptier interval = " +
>              this.emptierInterval + " minutes.");
>    }
> {code}
> this.deletionInterval and this.emptierInterval are in miliseconds, but the LOG.info tells
that they are in minutes.
