Hello everyone. I want to install gui in the sandbox hdp 2.6, i run it with virtual box, i install the vbox guest additions. I also tried to follow the steps on this site : http://ihorbobak.com/index.php/2015/05/07/how-to-add-gnome-gui-to-hortonworks-sandbox-2-1/ who describes the installation of gui in sandbox 2.1 but it doesn't exist anymore. When i'm connected on ssh to the sandbox, i tried to run startx but i get an error that you can see below. Otherwise there is something strange that i want to understand and i think this could be the cause of the problem : when i'm connected to the sandbox via ssh, i'm on centos 6.9, but when i'm directly connected with the sandbox window i'm on centos 7.2 Why this is not the same system ? And how can i install gui on this sandbox ? The error when i run startx when i'm connected to ssh : [root@sandbox ~]# startx xauth: file /root/.serverauth.19708 does not exist X.Org X Server 1.17.4 Release Date: 2015-10-28 X Protocol Version 11, Revision 0 Build Operating System: c1bm 3.10.0-514.10.2.el7.x86_64 Current Operating System: Linux sandbox.hortonworks.com 4.11.0-1.el7.elrepo.x86_64 #1 SMP Mon May 1 09:01:59 EDT 2017 x86_64 Kernel command line: BOOT_IMAGE=/vmlinuz-4.11.0-1.el7.elrepo.x86_64 root=UUID=0b65bf9e-d227-48fb-be57-b4d72368dcf0 ro crashkernel=auto rhgb quiet LANG=en_US.UTF-8 Build Date: 22 March 2017 02:59:47AM Build ID: xorg-x11-server 1.17.4-16.el6.centos Current version of pixman: 0.32.8 Before reporting problems, check http://wiki.centos.org/Documentation to make sure that you have the latest version.

Hello everyone there is my problem : In order to automated kerberos installation i follow this tutorial for HDP sandbox 2.4 : https://community.hortonworks.com/articles/29203/automated-kerberos-installation-and-configuration.html I already try to set up it manually but without success because of a connection problem with the kdc when i try to configure it on ambari web interface. So i try the tutorial but now i have this problem when i launch it : 017-07-27,13:50:41 Enabling Kerberos % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 137 513 102 513 0 172 12 4 0:00:42 0:00:40 0:00:02 78 HTTP/1.1 400 Bad Request X-Frame-Options: DENY X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff Cache-Control: no-store Pragma: no-cache Set-Cookie: AMBARISESSIONID=ka633m5h9um01jqyy6uamrb18;Path=/;HttpOnly Expires: Thu, 01 Jan 1970 00:00:00 GMT User: raj_ops Content-Type: text/plain Content-Length: 513 Server: Jetty(8.1.19.v20160209) { "status" : 400, "message" : "java.lang.IllegalArgumentException: Invalid KDC administrator credentials.\nThe KDC administrator credentials must be set as a persisted or temporary credential resource.This may be done by issuing a POST (or PUT for updating) to the /api/v1/clusters/:clusterName/credentials/kdc.admin.credential API entry point with the following payload:\n{\n \"Credential\" : {\n \"principal\" : \"(PRINCIPAL)\", \"key\" : \"(PASSWORD)\", \"type\" : \"(persisted|temporary)\"}\n }\n}" I try to solve the problem by fixing manually the credential but the script seems to modify (it changes my persisted credential by a temporary credential) it and i can't find where it do it (and also i don't know how to see the principal of the credential to understand maybe why it's not working). I also want to specify that in 2.6 ambari's log are : user : raj_ops password : raj_ops I think i configure my ambari.props correctly : CLUSTER_NAME=Sandbox AMBARI_ADMIN_USER=raj_ops AMBARI_ADMIN_PASSWORD=raj_ops AMBARI_HOST=localhost KDC_HOST=localhost REALM=EXAMPLE.COM KERBEROS_CLIENTS=localhost I have no more ideas on how to solve the problem please help me ^^ ...
