Hi, Can you try restarting CM agent using the following cmd: # service cloudera-scm-agent restart   Then restart NM from CM. Let me know if that works.   Note: do not start CM agent using /etc/init.d script directly ... View more

Hi, Instructions on yum repo installation can be found here [1]. You can get the repo file for example for RHEL 7 from here for example [2].   [1] - https://www.cloudera.com/documentation/enterprise/latest/topics/cdh_ig_cdh5_install.html#topic_4_4_1__p_32 [2] - https://archive.cloudera.com/cdh5/redhat/7/x86_64/cdh/cloudera-cdh5.repo?_ga=1.8210228.728334008.1433982308 ...

Hi, the reason for this has to do with the fact that you need to upgrade CM to 5.5. CM will not allow you to upgrade CDH to 5.5 until you upgrade CM to 5.5 first.   Per the documentation [1]: "The Cloudera Manager minor version must always be equal to or greater than the CDH minor version because older versions of Cloudera Manager may not support features in newer versions of CDH. For example, if you want to upgrade to CDH 5.4.8 you must first upgrade to Cloudera Manager 5.4 or higher."   [1] - http://www.cloudera.com/documentation/enterprise/5-5-x/topics/cm_mc_upgrading_cdh.html#cmig_topic_10 ...

So just to clarify: 1. You have a vm host which you have VirtualBox installed. 2. You setup an Ubuntu vm guest and placed the CM installation file on that Ubuntu vm guest 3. You were able to run the installer successfully (./cloudera-manager-installer.bin) from the command line 4. You then opened a browser and went to what URL (http://hostname:7180)? Which hostname/IP did you point to?    Also, make sure your DNS resolution is working fine.   -Hazem ... View more

What error do you see when you put your ip address in the wizard on your browser? Also, make sure iptables is turned off.   You can also check your /var/log/cloudera-scm-server/cloudera-scm-server.log log file. You will see attempts to SSH into your vm guest when you click Search. Below is a snippet of how mine looks when I hit search:   -Hazem     2014-04-25 12:17:09,163 INFO [454338303@scm-web-5:node.NodeScannerService@287] Request 2 contains 1 nodes 2014-04-25 12:17:09,163 INFO [454338303@scm-web-5:node.NodeScannerService@383] Existing scan of node 10.7.0.175 is too old, rescanning 2014-04-25 12:17:09,163 INFO [454338303@scm-web-5:node.NodeScannerService@291] Finished submitting request 2 2014-04-25 12:17:09,168 INFO [NodeScannerThread-2:node.NodeScanner@219] Beginning scan of node 10.7.0.175 and port 22 2014-04-25 12:17:09,172 INFO [NodeScannerThread-2:node.NodeScanner@243] Canonical hostname is 10.7.0.175 2014-04-25 12:17:09,172 INFO [NodeScannerThread-2:node.NodeScanner@256] Connecting to remote host 2014-04-25 12:17:09,173 INFO [NodeScannerThread-2:node.NodeScanner@277] Disconnecting from remote host 2014-04-25 12:17:09,173 INFO [NodeScannerThread-2:node.NodeScanner@293] Connecting to ssh service on remote host 2014-04-25 12:17:09,174 INFO [454338303@scm-web-5:node.NodeScannerService@124] Request 2 returning 0/1 scans 2014-04-25 12:17:09,177 INFO [NodeScannerThread-2:transport.TransportImpl@152] Client identity string: SSH-2.0-SSHJ_0_8 2014-04-25 12:17:09,187 INFO [NodeScannerThread-2:transport.TransportImpl@161] Server identity string: SSH-2.0-OpenSSH_5.3 2014-04-25 12:17:09,189 INFO [NodeScannerThread-2:transport.KeyExchanger@195] Sending SSH_MSG_KEXINIT 2014-04-25 12:17:09,190 INFO [reader:transport.KeyExchanger@357] Received SSH_MSG_KEXINIT 2014-04-25 12:17:09,214 INFO [reader:kex.DHG14@110] Sending SSH_MSG_KEXDH_INIT 2014-04-25 12:17:09,217 INFO [reader:transport.KeyExchanger@370] Received kex followup data 2014-04-25 12:17:09,217 INFO [reader:kex.DHG14@120] Received SSH_MSG_KEXDH_REPLY 2014-04-25 12:17:09,241 INFO [reader:transport.KeyExchanger@203] Sending SSH_MSG_NEWKEYS 2014-04-25 12:17:09,241 INFO [reader:transport.KeyExchanger@385] Received SSH_MSG_NEWKEYS 2014-04-25 12:17:09,243 INFO [NodeScannerThread-2:node.CmfSSHClient@686] Key exchange took 0.053 seconds 2014-04-25 12:17:09,243 INFO [NodeScannerThread-2:node.NodeScanner@315] Disconnecting from ssh service on remote host 2014-04-25 12:17:09,243 INFO [NodeScannerThread-2:node.NodeScanner@208] Connected to SSH on node 10.7.0.175 with port 22 (latency PT0.001S) 2014-04-25 12:17:09,245 INFO [NodeScannerThread-2:node.NodeScannerService@175] Request 2 observed finished scan of node 10.7.0.175 2014-04-25 12:17:10,196 INFO [454338303@scm-web-5:node.NodeScannerService@124] Request 2 returning 1/1 scans   ...
