Chris Nauroth commented on HDFS-6344:
-------------------------------------

Sorry I'm coming in late after the patch is already committed.

The defaults chosen in this patch look reasonable to me with consideration of 
the use case driving xattrs.  However, I wonder if the property name should 
include "fs-limits" for consistency with the other metadata limitation 
properties: {{dfs.namenode.fs-limits.max-component-length}} and 
{{dfs.namenode.fs-limits.max-directory-items}}.  What do you think?

> Maximum limit on the size of an xattr
