Daryn Sharp updated HDFS-4553:
------------------------------
Attachment: HDFS-4553.branch-23.patch
Issue already fixed on trunk via HDFS-3667 that added retry support to webhdfs.
The fix was extraneous to the retry changes, so I've extracted the couple of
relevant lines.
No test is included. It's a simple change, HDFS-3667 included no test, and it
sure doesn't look simple to test.
I have manually verified it on a secure cluster. The issue was originally
uncovered by a 401 Unauthorized response. It now handles that case correctly.
