Tsz Wo (Nicholas), SZE commented on HDFS-5228:
----------------------------------------------
Chris, thanks for posting a patch. I do think that the best solution is to
revert HADOOP-9418, which seemed not well tested. HADOOP-9418 first broke
HADOOP-9761 and then this. As Andrew said, "... I think some number of bugs
like this are unavoidable as symlinks was a pretty big change that required
touching basically all the client API code. ..." We should not let HADOOP-9418
destabilize 2.1.1.
> The RemoteIterator returned by DistributedFileSystem.listFiles(..) may throw
> NPE
