How do I integrate Keycloak as identity and access management tool instead of Apache Knox for ambari? Ambari uses AD for external authentication.

When a yarn application is about to run, it needs to send a request for the container allocation. How does it know that it needs certain amount of resource to run in certain amount of time. How do I get that by REST api?

I'm getting bad request as response with message "Attempted to add unknown hosts to a cluster. These hosts have not been registered with the server"

When HDFS does not have enough memory because it is running some other jobs or when the HDFS storage is almost full, When a new Hive queries is requested by a client, how this query is affected in terms of performance? Does adding a new host improve the performance?

In the http://<server>:<port>/api/v1/bootstrap/requestId, the status is SUCCESS , but the new host is not shown in http://<server>:<port>/api/v1/clusters/<clusterName>/hosts

I want to add new host running CentOS 7 on vm in windows to cluster. I was able to ssh without any password as 'root' from server to vm and from vm to server. The following error occurs while Running setup agent script... to add new host from ambari INFO:root:BootStrapping hosts ['xx.xx.xxx'] using /usr/lib/python2.6/site-packages/ambari_server cluster primary OS: redhat7 with user 'root'with ssh Port '5555' sshKey File /var/run/ambari-server/bootstrap/1/sshKey password File null using tmp dir /var/run/ambari-server/bootstrap/1 ambari: yy.yy.yyy; server_port: 8080; ambari version: 2.6.1.5; user_run_as: root Bootstrap to host xx.xxx.xx fails because previous action finished with non-zero exit code 255

How do I get the memory usage avg.?

amarn_ucs2014 · ‎08-14-2018

Say, for last 5 minutes what is the cpu usage for 5 minutes averaged across all nodes in the cluster? I can see that in Ambari, but I want information in the given time range and I should be able to get that information with an API call.

amarn_ucs2014 · ‎08-07-2018

I just want to know if there is any new application is running.
