Sangjin Lee commented on HADOOP-10295:
--------------------------------------
The patch looks good.
Just one question. I see now there is an explicit call to create the permission
in copyToTmpFile(). What is the nature of this change? Was the same thing being
done implicitly and it is just made explicit, or is there another reason?
> Allow distcp to automatically identify the checksum type of source files and
> use it for the target

> Currently while doing distcp, users can use "-Ddfs.checksum.type" to specify
> the checksum type in the target FS. This works fine if all the source files
> are using the same checksum type. If files in the source cluster have mixed
> types of checksum, users have to either use "-skipcrccheck" or have checksum
> mismatching exception. Thus we may need to consider adding a new option to
> distcp so that it can automatically identify the original checksum type of
> each source file and use the same checksum type in the target FS.
