After installing Hortonworks sandbox 2.4 I can not find out how to restart service like hbase Hdfs from Ambari.
So what I need to know how to restart hadoop services from Ambari ?
In SandBox 2.4 you have to reset the username and the password for the user Admin
I think you are logging in as maria_dev where this user have the read-only permission, if this is the case,
what you need to do is lancing the script ambari-admin-password-reset , enter username and a password for the user admin and login by this user.

I have an Azure Kubernetes Service. I deployed the Apache Ignite image on it.
It works well and I'm using ThinClient to connect to the Ignite. Also, authentication has been enabled.
In the first deployment, Ignite creates a superuser that name and password are "ignite".
I created my own user and tested to connection. It succeeded.
I would like to delete the user created by Apache Ignite, but I couldn't do it.
How can I delete the user?
The default superuser can't be removed, but you should be able to change the default password ALTER USER "ignite" WITH PASSWORD 'newPassword';

I chose the NextCloud for that, installed it on Ubuntu server as per documentation. Now I want to configure the LDAP authentication but that option is not available on the admin pages.
This is the first time I ever tried NextCloud. What am I missing, is that a paid-for feature?
Do you have the php ldap module? If not try something like apt-get install php5-ldap.
NextCloud should have a setup form for the LDAP integration. Then you just put in the server information and credentials for the ldap. A free test ldap that is available for testing at Btech Online ldap.
I have set up rabbitMQ federation between two machines A and B, bi-direction,
but have the error
{auth_failure,"ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile."}
in the log file, it seems the federation amqp need to access through guest/guest credential, this comes to the question here:
rabbitMQ guest login failed
with existing solution to set up test/test here :
Can't access RabbitMQ web management interface after fresh install
I tried to make guest/guest also work from another machine by running :
rabbitmqctl set_permissions -p / guest "." "." ".*"
but still fail to login via guest/guest on another machine,
in the rabbitMQ management web UI, the user test and guest look all the same:
Name
Tags
Can access virtual hosts Has password
guest
administrator / ●
test
administrator / ●
but why I still can't loging with guest/guest on another machine? (test/test works fine)
You are not listing what version you use, but guesstimating from your post time, I would say the issue is probably because in v 3.3.0 (released in early April 2014) they disabled guest user login remotely (see release notes here), AND it looks like at some point around that time there was a change either in the way federation is supposed to be setup, or simply the yanking of the guest user made it behave differently.
Anyway, to resolve this, make sure you create your upstream with an URI in the following form:
amqp://your_user:your_users_password#rabbit-node-FQDN.your.domain.com/your_vhost
the key is in the your_user:your_users_password string - that was not required before 3.3 (and it still may work without it should you enable the guest user... but I don't care to try that)

I am starting to look into configuring an SVN server using Apache2 and mod_dav_svn on Red Hat Linux. I want Apache to handle authenticating the users that access the repository. Is there a way to have Apache authenticate against the user credentials maintained by the OS? This way I can allow all of my users on the server to use the same account to access SVN and to login to the system via SSH.
Previously our SVN server was hosted on a Windows server and we were able to use AuthType SSPI to perform our authentication against the Windows Active Directory server which will no longer be available to us. (Note: this is a restriction due to our network security and is not with my control)
Ultimately the solution I found to this problem was to configure mod-authnz_external to work with pwauth. Following the instructions on those two sites seems to have resulted in a working solution.
