Todd Lipcon updated HDFS-3522:
------------------------------
Release Note: getBlockLocations(), and hence open() for read, will now
throw SafeModeException if the NameNode is still in safe mode and there are no
replicas reported yet for one of the blocks in the file.
Hadoop Flags: Incompatible change,Reviewed (was: Reviewed)
Marking as incompatible change, since this will now throw an exception for this
where it didn't before. I think it's fine, but we should call it out.
> If NN is in safemode, it should throw SafeModeException when
> getBlockLocations has zero locations
