Hi,
I'm using Apache Ambari 2.7.5 to setup and maintain a Hadoop cluster on Centos
7.9. Already managed to add a namenode and a datanode to local host (of
ambari-master) but failed to add another datanode, it fails with warning
encountered and in /var/lib/ambari-agent/data/output-466.txt the last lines
are:
2023-05-14 08:20:01,741 - FS Type: HDFS
2023-05-14 08:20:01,741 - XmlConfig['core-site.xml'] {'group': 'hadoop',

2023-05-14 08:20:01,769 - Could not load 'version' from
/var/lib/ambari-agent/data/structured-out-466.json
Since all necessary packages was already installed by ambari agent and all
configs been generated, i tried to start the datanode manually using "hdfs
--daemon start datanode" after creatig hdfs dir in /home and chown the hdfs
directory and it successfully started and registered to namenode.
How could i find out why ambari does not finish the task of adding the
datanode? How could i find out the steps that ambari is executing to install
datanode and in which step its stucking?
Thanks in advance
