Adam Antal commented on HDFS-14195:
-----------------------------------
Hi,
Thanks for the patch [~suxingfate]. Yes, thanks for the items having been
addressed.
Some cosmetics there:
* {{java.io.*}} wildcard import is still there. It's matter of taste, but I
prefer explicitly stating the used imports.
* Also could you remove the extra line there:
{code:java}
try (
ByteArrayInputStream input =
new ByteArrayInputStream(output.toByteArray());
{code}
I'm +1 (non-binding) on committing this, thanks again for the work.
[~jojochuang], could you please take a look and commit this, if you agree. Also
[~smeng], if you have time for the review I'd be glad, since you have great
knowledge around the OIV tool.

> There is lacking of a method to get all folders and files with sort of
> specified storage policy via command line, like ALL_SSD type.
> By adding storage policy id to oiv output, it will help with oiv
> post-analysis to have a overview of all folders/files with specified storage
> policy and to apply internal regulation based on this information.
>
> Currently, for PBImageXmlWriter.java, in HDFS-9835 it added function to print
> out xattr which including storage policy already.
