> Usage: hadoop fs -expunge
> Empty the Trash. Refer to the HDFS Architecture Guide for more information on the Trash feature.
> this description is confusing. It gives user the impression that this command will empty trash, but actually it only removes old checkpoints. If user sets a pretty long value for fs.trash.interval, this command will not remove anything until checkpoints exist longer than this value.
