*Update* It seems like hostname issue. The hostname -f command showed localhost instead of FQDN. This is weird as both the hostname and hostnamectl showed FQDN. Updating the hosts file did the trick. So instead of 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 FQDN I updated it to 127.0.0.1 FQDN localhost localhost.localdomain localhost4 localhost4.localdomain4 This resolved the weird issue with the hostname command, and the server registraion completed successfully.

I am facing the exact same issue. Asked a new question before I saw this one. For me the versions are the same, still the problem persists. Could not find anything useful in the server logs or agent logs, so decided to start from zero again. I removed ambari-agent from the new node and all the files and tried to install from ambari UI. It errors out now. Server Log snippet below the snapshot: Log shows the following:

I am trying to add additional node to an AWS ambari server on AWS. I have installed ambari-agent on the new node and is up and running. But when I try to add the node to my cluster through ambari, it fails with an error (see screenshot-1) I am not able to find the correct logs in the ambari server. Any ideas where the logs will be? What is the problem that might have happened?

Geoffery, Jay. Thanks a lot for your replies. I went through the logs and found out that the JVM engine is not able to start with insufficient memory. Bumped up the server. Now it is working. Thanks a lot

Hello Geoffery, Thank you for coming back. Yes the folder is available and the permissions look correct. drwxr-xr-x. 2 hdfs hadoop 6 Apr 6 20:43 /hadoop/hdfs/data/ This is a single node cluster so there are no different data and name nodes.

Please tell me if you need the logs, I will attach it here. There is a file limitation so I am not attaching anything for now.

I installed a HDP 2.6 in Centos using the web repo. I tried to start 4 services: Hadoop, Smartsense, Ambari-metrics and Zookeeper. All the services got installed but none could start. After the installation, during cluster deployment from the web UI, the services are Installed but did not start. ambari-agent log shows the following : ERROR 2018-04-06 20:41:19,502 script_alert.py:123 - [Alert][datanode_unmounted_data_dir] Failed with result CRITICAL: ['The following data dir(s) were not found: /hadoop/hdfs/data\n'] WARNING 2018-04-06 20:41:19,508 base_alert.py:138 - [Alert][namenode_hdfs_blocks_health] Unable to execute alert.
