As it turns out, patching to HDP 3.0.1 fixed this issue.

Ambari 2.7/HDP 3.0/Knox 1.0.0 I am unable to access the Knox Admin UI: Problem accessing /gateway/manager/admin-ui. Reason: Not Found All default topologies are giving the same result, including webhdfs. The configuration with ldaps/https was working great in previous versions of HDP 2.x, but does not work in HDP 3.0. From the docs, it looks like I need to get the admin-ui working in order to fix this. Does anyone know why the default installation of Knox under HDP 3.0.0 is lacking the admin-ui application? Thanks.

hi Selvan, Thanks for the response. I have attempted the operation while logged into the Ambari UI as admin as well as my own user. The HDFS directy exists and is writable for the user I'm logged in as. If it were not, I would not be able to list files and create directories. The cluster is not Kerberized. I have since built a new cluster on CentOS 7 and it works there, even though the HDFS Namenode, Datanode, and Ambari View settings/configuration is completely identical. The broken cluster is built on Ubuntu 16.04.

I am running Ambari 2.6 and setup a new files view on my local cluster. I am able to list/create/delete directories. I am also able to list/delete files. I am unable to upload or download files, however. My ambari-server is running as root and I have the hadoop.proxyuser.root.groups set to * and the hadoop.proxyuser.root.hosts set to *. I have tried setting them to actual values, but get the same error. Any ideas how to get upload/download to work? I get this error in the Ambari UI: Unexpected HTTP response: code=503 != 201, op=CREATE, message=Service Unavailable java.io.IOException: Unexpected HTTP response: code=503 != 201, op=CREATE, message=Service Unavailable

My user has access to HDFS, but only his own space. As I mentioned in the question, I know it works when I put the regular user into the HDFS group. I do not want to do this, because it grants the user access to everyone's HDFS space, just like the hdfs user. I want to get this working without the user being a member of the hdfs group. Is this possible?

I am unable to load data into hive from a file that exists on hdfs using hive interactively. If I place the user in the hdfs group, this works, but, of course, grants way more privileges than I want on hdfs for a basic user. Can interactive hive commands access HDFS without being a member of the group? ======================================================================== user@server:~$ hdfs dfs -put /home/user/test99.csv /user/user/test99.csv

@Vipin Rathor What are your thoughts on the issue I'm experiencing?

Hi @Vipin Rathor, I use curl to put a file into WebHDFS through Knox. The file could be
any type so far. I've tried many types. The hdfs commands show the
files are fine. Copying local with hdfs never fails to preserve the
md5sum. Using curl to get the file using the direct port 50070 WebHDFS
URL works flawlessly. Only the WebHDFS URL through Knox causes the
issues and only for gzipped files. Here is the output requested: > Host: master.example.com:9443 > Authorization: Basic YmZncmVlbjppbHU9NFV4dQ== > User-Agent: curl/7.47.0 > Accept: */* > < HTTP/1.1 200 OK < Date: Mon, 14 Aug 2017 21:57:22 GMT < Set-Cookie: JSESSIONID=jhnuvevog6cp1aqkt3duexl4w;Path=/gateway/default;Secure;HttpOnly < Expires: Thu, 01 Jan 1970 00:00:00 GMT < Set-Cookie: rememberMe=deleteMe; Path=/gateway/default; Max-Age=0; Expires=Sun, 13-Aug-2017 21:57:22 GMT < Access-Control-Allow-Methods: GET < Access-Control-Allow-Origin: * < Content-Type: application/octet-stream < Connection: close < Server: Jetty(9.2.15.v20160210) < { [15935 bytes data] 100 2143k 0 2143k 0 0 2591k 0 --:--:-- --:--:-- --:--:-- 2589k * Closing connection 0 Here is the observed md5sum behaviour for the uploaded source file,

Whenever I upload a file through Knox to WebHDFS, the file remains identical to the source file. However, whenever I download/get the file back via Knox gateway, if the file is gzip compressed, it is modified. The chksum and size changes on the archive. How can I get Knox to stop this behavior? It does not happen with any other file type.

Thanks, Pierre. That did the trick. Not sure how I missed it on my searches.
