Hi @Ancil McBarnett, many thanks for your explanation. I could successfully connect to another clusters DemoLDAP with DirectoryStudio (unfortunately I have no permissions to install JExplorer) by using the default user DN. I will double check the manually adjusted users in the non-working cluster, or maybe the ssh-tunnel/firewall topic is causing issues ?!?! (see my reply to Kevin Minder) Thanks and regards, Gerd

Thanks @Kevin Minder for your feedback. Indeed I was able to connect to another cluster with the default user DN provided by DemoLDAP. I guess the issue may be caused by the difference of connecting to the LDAP server. In the non-working one I have to create a ssh-tunnel to port 33389 due to firewall issue, whereas in the working cluster there is no firewall in front and I can directly access it. But I have no explanation what exactly can go wrong there, since accessing the port isn't an issue (see screenshot 1)...?! For now it is o.k, I'll dive into that later on... Thanks

Hello, I wanted to connect with ApacheDirectoryStudio to the DemoLDAP server included in Knox, just to have a graphical way of checking for users. Network settings are fine => But I got stuck in providing correct bind credentials.....what to provide there ?!?! I also tried to provide the following bind dn: uid=admin,ou=users,dc=hdp,dc=XYZ,dc=sit , but it fails also, with error Any hint highly appreciated 😉

Thanks @Kevin Minder for your explanation. Is it possible to proxy the NN / RM Webpage through Knox?....Just to put Access to those webuis behind HTTPS

Hi @Artem Ervits, @Neeraj Sabharwal just to give you an update on this: - yes, there was/is enough space in /usr and the dir /usr/hdp/2.2.5.2-2 has been created - due to time pressure I decided to start again from scratch with ambari 2.0.1 (the combination which I used for earlier clusters as well), right now it looks good, also that particular host is up as a worker node - to cleanup all the nodes I used the hostcleanup python script and some additional directory deletions (due to non-standard directories, e.g. for logs) I will do the Ambari upgrade later on. Thanks for all you efforts

Hi @Artem Ervits, thanks for this input. I tried it, but the link named 'current' hasn't been created, seems like the hdp-select command didn't do anything?!?! $ ls -al /usr/hdp total 12 drwxr-xr-x 3 root root 4096 Jan 12 20:28 . drwxr-xr-x 16 root root 4096 Jan 12 20:28 .. drwxr-xr-x 13 root root 4096 Jan 13 08:56 2.2.4.2-2 $ /usr/bin/hdp-select set all 2.2.4.2-2 $ ls -al /usr/hdp total 12 drwxr-xr-x 3 root root 4096 Jan 12 20:28 . drwxr-xr-x 16 root root 4096 Jan 12 20:28 .. drwxr-xr-x 13 root root 4096 Jan 13 08:56 2.2.4.2-2

Hi @Alejandro Fernandez, thanks for your answer, but it is not exactly how it should look like 😉 (maybe you are referring to an older version, before adding the version number into the installation directory tree). Currently, the linking should be: /usr/hdp/current -> /usr/hdp/2.2.4.2-2 and /usr/hdp/2.2.4.2-2/hadoop/conf -> /etc/hadoop/conf

Maybe I will start completely from scratch with a fresh installation. Which Ambari version would you recommend for setting up a fresh HDP 2.2.4 ? Yes, unfortunately I have to use that HDP version, an upgrade is planned for later this year 😉

@Neeraj Sabharwal ok, tried doing it again after removing any hadoop_* packages on that node from a previous run, but again: ... 2016-01-12 20:29:26,813 - Skipping XmlConfig['core-site.xml'] due to only_if 2016-01-12 20:29:26,814 - Can only link configs for HDP-2.3 and higher. and then: $ ls -al /usr/hdp total 12 drwxr-xr-x 3 root root 4096 Jan 12 20:28 . drwxr-xr-x 16 root root 4096 Jan 12 20:28 .. drwxr-xr-x 13 root root 4096 Jan 12 20:29 2.2.4.2-2 hence, the link 'current' is missing...thereby the datanode fails at starting up

Hi @Neeraj Sabharwal, thanks for getting back that quickly. Referring to page: http://docs.hortonworks.com/HDPDocuments/Ambari-2.1.2.1/bk_Installing_HDP_AMB/content/_determine_stack_compatibility.html I am assuming that Ambari 2.1.2 is supporting HDP 2.2.4 ?!?! Which version should I use instead ?
