Hi I am trying to install cdh and its associated packages in my centos 7 machine. when I was installing the cloudera manager I got the errorInstallation failed. Failed to authenticate.. when i searched the community I can see that its due to ssh misconfiguration. When I tried to run ssh@localhost I have no problems .Please help me how to proceed further.   Please find the log below   2016-05-11 03:00:00,037 INFO com.cloudera.cmf.scheduler-1_Worker-1:com.cloudera.cmf.service.ServiceHandlerRegistry: Executing command GlobalPoolsRefresh BasicCmdArgs{scheduleId=1, scheduledTime=2016-05-11T07:00:00.000Z}. 2016-05-11 03:00:00,038 INFO com.cloudera.cmf.scheduler-1_Worker-1:com.cloudera.cmf.scheduler.CommandDispatcherJob: Skipping scheduled command 'GlobalPoolsRefresh' since it is a noop. 2016-05-11 03:05:27,534 INFO StaleEntityEviction:com.cloudera.server.cmf.StaleEntityEvictionThread: Reaped total of 0 deleted commands 2016-05-11 03:05:27,535 INFO StaleEntityEviction:com.cloudera.server.cmf.StaleEntityEvictionThread: Found no commands older than 2014-05-12T07:05:27.534Z to reap. 2016-05-11 03:05:27,536 INFO StaleEntityEviction:com.cloudera.server.cmf.StaleEntityEvictionThread: Wizard is active, not reaping scanners or configurators 2016-05-11 03:12:21,391 INFO 416732421@scm-web-63:com.cloudera.server.cmf.node.NodeConfiguratorService: Creating request with id 27 2016-05-11 03:12:21,392 INFO 416732421@scm-web-63:com.cloudera.server.cmf.node.NodeConfiguratorService: Adding password-based configurator for localhost 2016-05-11 03:12:21,392 INFO 416732421@scm-web-63:com.cloudera.server.cmf.node.NodeConfiguratorService: Submitted configurator for localhost with id 0 2016-05-11 03:12:21,392 INFO NodeConfiguratorThread-27-0:com.cloudera.server.cmf.node.NodeConfiguratorProgress: localhost: Transitioning from INIT (PT0S) to CONNECT 2016-05-11 03:12:21,392 INFO NodeConfiguratorThread-27-0:net.schmizz.sshj.transport.TransportImpl: Client identity string: SSH-2.0-SSHJ_0_14_0 2016-05-11 03:12:21,402 INFO NodeConfiguratorThread-27-0:net.schmizz.sshj.transport.TransportImpl: Server identity string: SSH-2.0-OpenSSH_6.6.1 2016-05-11 03:12:21,460 INFO NodeConfiguratorThread-27-0:com.cloudera.server.cmf.node.NodeConfiguratorProgress: localhost: Transitioning from CONNECT (PT0.068S) to AUTHENTICATE 2016-05-11 03:12:21,501 WARN NodeConfiguratorThread-27-0:com.cloudera.server.cmf.node.NodeConfigurator: Could not authenticate to localhost net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods at net.schmizz.sshj.SSHClient.auth(SSHClient.java:232) at net.schmizz.sshj.SSHClient.auth(SSHClient.java:208) at com.cloudera.server.cmf.node.NodeConfigurator.connect(NodeConfigurator.java:341) at com.cloudera.server.cmf.node.NodeConfigurator.configure(NodeConfigurator.java:889) at com.cloudera.server.cmf.node.NodeConfigurator.run(NodeConfigurator.java:935) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) 2016-05-11 03:12:21,501 INFO NodeConfiguratorThread-27-0:com.cloudera.server.cmf.node.NodeConfiguratorProgress: localhost: Setting AUTHENTICATE as failed and done state 2016-05-11 03:12:21,501 INFO NodeConfiguratorThread-27-0:net.schmizz.sshj.transport.TransportImpl: Disconnected - BY_APPLICATION 2016-05-11 03:15:27,546 INFO StaleEntityEviction:com.cloudera.server.cmf.StaleEntityEvictionThread: Reaped total of 0 deleted commands 2016-05-11 03:15:27,547 INFO StaleEntityEviction:com.cloudera.server.cmf.StaleEntityEvictionThread: Found no commands older than 2014-05-12T07:15:27.546Z to reap. 2016-05-11 03:15:27,548 INFO StaleEntityEviction:com.cloudera.server.cmf.StaleEntityEvictionThread: Wizard is active, not reaping scanners or configurators   Thanks in advance !! ...
