Eli Collins commented on HADOOP-8816:
-------------------------------------
+1 looks good
How about adding a comment to the test where you check the 63kb length that the
buffer size set is for ALL headers which is why you're only adding a 63kb
header when the limit is 64kb (leaving 1kb room for other headers). No need to
spin a new patch for just adding this comment IMO.

> The HTTP Authentication: header is too large if using kerberos and the
> request is rejected by Jetty because Jetty has a too low default header size
> limit.
> Can be fixed by adding ret.setHeaderBufferSize(1024*128); in
> org.apache.hadoop.http.HttpServer.createDefaultChannelConnector
