@tita titouf Couple of things are strange and you should check: 1. We see in your screenshot '14995-capture-decran-2017-05-02-a-181239.png' that the IP Address resolution is not happening for host "hdfs-hdp.pfe.test.com" and hence we see: WARN [ambari-heartbeat-processor-0] HeartbeatProcessor:701 - Received a live status with invalid payload service, clusterName=pfe, serviceName=HDFS, componentName=NAMENODE, hostname=hdfs-hdp.pfe.test.com, error=Name is null So please check if your NameNode is having correct hostname defined in HDFS configs. Check the output of the following commands to see if IPAddress resolution is correct: # ifconfig # hostname -f . Also verify if the ambari-agent log shows any ERROR/WARNING in this host? # less /var/log/ambari-agent/ambari-agent.log And check the RPM of ambari-agent if it's version is same as ambari-server. Example: # rpm -qa | grep ambari ambari-agent-2.4.0.0-1225.x86_64 ambari-server-2.4.0.0-1225.x86_64 . 2. The following error indicates that you might not have internet access from ambari server/agent hosts. So you should first check if the internet access is there or not else you need to make sure that at least Off line Local repository is configured as mentioned in: http://docs.hortonworks.com/HDPDocuments/Ambari-2.5.0.3/bk_ambari-installation/content/setting_up_a_local_repository_with_no_internet_access.html ERROR [ambari-client-thread-225] BaseManagementHandler:67 - Bad request received: Could not access base url . http://public-repo-1.hortonworks.com/HDP/ubuntu12/2.x/updates/2.4.0.0 . public-repo-1.hortonworks.com You can verify the same. Check if the ambari repo is accessible and if youa re able to access the "hdp.repo" file from your cluster nodes/ambari host. # ping public-repo-1.hortonworks.com # wget http://public-repo-1.hortonworks.com/HDP/ubuntu12/2.x/updates/2.4.0.0/hdp.repo . 3. The error that you are getting while attempting to MySQL Database indicates wither you do not have correct permissions specified for mysql user or you might be entering incorrect credentials (or your Ambari DB is not using the default password 'bigdata'. Please check the following section of the DOC to know what pre-configuration is needed in order to use MySQL as ambari DB. https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.0.3/bk_ambari-administration/content/using_ambari_with_mysql.html # mysql -u ambari ambari -pbigdata ERROR 1045 (28000): Access denied for user 'ambari'@'localhost' (using password: YES) Also please check the file specified in the following property to see if the password is correct. # grep 'server.jdbc.user.passwd' /etc/ambari-server/conf/ambari.properties server.jdbc.user.passwd=/etc/ambari-server/conf/password.dat # cat /etc/ambari-server/conf/password.dat bigdata . ...

@tita titouf I know you got the answer in this other post, but I want to provide it for others that might stop by. https://community.hortonworks.com/questions/95905/isilon-one-fs-and-hortonworks-deployment.html#answer-98919 Ambari provides a warning in the system check. But you can ignore this warning and proceed with installation. ... View more

Just to be clear, do not install Ambari Metrics on Isilon, Isilon OneFS v 8.0.1.1 provides Isilon specific updates to Ambari Metrics automatically via OneFS. Just make sure you use OneFS 8.0.1.x code as it has the latest updates for Ambari Metrics. If you are just adding Ambari Metrics to HDP and you didn't select it during the initial install, just use the add service wizard in Ambari to add Ambari Metrics to your master node (not Isilon!). If the add service wizard is failing you, check you /etc/yum.repos.d to make sure you are pointing to the correct repositories for your version of HDP. Also make sure you have the appropriate internet access for yum to connect to the external repositories. ... View more
