Hi Team,

During installation from ambari, the HDP clients successfully got installed in one of our datanodes. However it seems like there is some error in datanode which we are not able to troubleshoot the issue. The heartbeat response is receiving as can be seen in ambari-agent.log file.I am attaching the screenshot for your kind review. Can you please help us here??

1. Are the Ambari agents running? Please check their status.

2. Please check ambari-agent, ambari-metrics-monitor and ambari-server logs for recent ERROR. These logs are usually found under /var/log/ where they run. Each node in the cluster has the agent and the monitor. The ambari-server log is on the ambari server host. Log files rotate. Check the latest without a data stamp.

You can try something like

cat ambari.log | grep ERROR

or

tail -1000 ambari.log | grep ERROR

Just look at the timestamp to eliminate false positives.
