Josh Elser reopened HBASE-20579:
--------------------------------
If the chown/chgrp fail, the real exception is now not propagated for the user
to see.
{code:java}
+ try {
+ fs.setOwner(path, filesUser, filesGroup);
+ } catch (IOException e) {
+ throw new RuntimeException(
+ "set owner for file " + path + " to " + filesUser + ":" +
filesGroup + " failed");
}{code}
{code:java}
+ try {
+ fs.setPermission(path, perm);
+ } catch (IOException e) {
+ throw new RuntimeException(
+ "set permission for file " + path + " to " + filesMode + "
failed");
+ }{code}
Need to put an addendum on this..

> Components: mapreduce
> Affects Versions: 1.4.0, 1.5.0, 2.0.0
> Reporter: Jingyun Tian

> Priority: Minor
> Fix For: 3.0.0, 2.1.0

> ExportSnapshot need to copy snapshot manifest to destination cluster first,
> then setOwner and setPermission for those paths. But it's done with one
> thread, which lead to a long time to submit the job if your snapshot is big.
> I tried to make them processing in parallel, which can reduce the total time
> of submitting dramatically.
