It's not temporary files, it's any file that has been compacted away. If you
keep files around longer than { dfs.namenode.checkpoint.period}, then you have
a chance to recover in case your most recent checkpoint is corrupt.

Is there any reason that the default value for gc.trash.ignore is false? Is
there any downside to deleting GC'ed files completely?
Thanks in advance,
