> It means when SnapshotHFileCleaner begin to cleanup the archive folder, it reads the the snapshot dir to check if any links to hfiles exist, but when read the file /.hbase-snapshot/.tmp/frog_stastic_2016-08-17/.snapshotinfo, corrupt exception thrown out (not sure why the file corrupt), and cleanup will be failed.
> I think we should catch up the exception and delete the file to ensure cleanup will go on.
