Problem background and phenomenon

The installation cluster failed during the installation node phase:

Cause Analysis

Checking "/var/log/Bigdata/nodeagent/agentlog/agent.log" has the following error:

This problem is caused because the node that was installed in this cluster has not been uninstalled before, and this node is not installed during this installation, causing the node to continuously connect to the controller for authentication, causing the kerberos account to be locked, causing other nodes to fail to install.

You can view the "/var/log/Bigdata/okerberos/oms-krb5kdc.log" log on the primary OMS node to confirm which node is constantly connecting to the controller for authentication:

Among them, 10.67.149.73 and 10.67.149.75 are nodes that have been installed before, not nodes in this cluster.

Solution

Log in to the node that was not uninstalled before, perform the uninstallation of sh /opt/huawei/Bigdata/nodeagent/setup/uninstall.sh, and then reinstall the cluster.
