Fix Version/s: (was: 0.7.0)
0.6.0
> WEBHDFS with knox doesn't support PAT for OPEN operation
> --------------------------------------------------------
>
> Key: KNOX-520
> URL: https://issues.apache.org/jira/browse/KNOX-520
> Project: Apache Knox
> Issue Type: Bug
> Components: Server
> Affects Versions: 0.5.0
> Environment: Centos 6
> Hadoop 2.6
> Reporter: LINTE
> Assignee: Kevin Minder
> Fix For: 0.6.0
>

> Network topology :

> /==>
> knox1 ==\
> Load balancer
> = ==>
> Namenodes
> \==>
> knox2 ==/
> A VIP (dns : knox-server) is supported by the load balancer, listening on 443
> TCP port (HTTPS).
> knox1 and knox2 listen on 8443 TCP port (HTTPS).
> So the traffic is NATed/PATed from knox-server:443 to knox1:8443 or
> knox2:8443.
> When doing an open operation on a file with webhdfs API throught knox it
> fails beacuse of a bad redirection 307.
> First request from the client (authenticated)
> ==> https://knox-server/gateway/sandbox/webhdfs/v1/tmp/myfile?OP=OPEN
> Response for this request by knox :
> ==> Location:
> https://knox-server:8443/gateway/sandbox/webhdfs/v1/tmp/myfile?_=<my_access_token>
> So the Knox gateway response contains a redirection to the good dns
> (knox-server) but to the unPATed port (8443) it should be 443.
> Redirection should be like the first request :
> ==> Location :
> https://knox-server/gateway/sandbox/webhdfs/v1/tmp/myfile?_=<my_access_token>
