Arun C Murthy commented on HADOOP-9984:
---------------------------------------
I'd like some help understanding...
{blockquote}
We discussed alternatives to HADOOP-9984, but concluded that they weren't
workable.
We agreed that HADOOP-9972 (new symlink-aware API for globStatus) should get
into Hadoop 2 GA.
{blockquote}
If we can add HADOOP-9972 in a compatible manner, say by making a non-abstract
method which throws UnsupportedOperationException or some such, we can add that
into 2.3 itself, correct? Why hold hadoop-2.2 for it? Thanks.

> During the process of adding symlink support to FileSystem, we realized that
> many existing HDFS clients would be broken by listStatus and globStatus
> returning symlinks. One example is applications that assume that
> !FileStatus#isFile implies that the inode is a directory. As we discussed in
> HADOOP-9972 and HADOOP-9912, we should default these APIs to returning
> resolved paths.
