Utilizing snapshotdiff for distcp
Hello all,
It looks like HDFS-8828 implemented a way to utilize the snapshotdiff
output to feed distcp in some way. I haven't however found any
documentation explaining how to do this. Can anyone provide any information
on if this is possible, and if so how to appropriately execute a distcp
with the output?
Thanks,
Nick

You need to pass the -diff <older snapshot name> <newer snapshot name>
option (works only when -update is active). The newer snapshot name can
also be "." to indicate the current view.
