Hi All I have installed HDP 2.6 in RHEL 7.4 in Azure. The installation process is completed. But when I started the cluster Name node is going in safe mode. Due to that other services are not able to come up.. I tried to manually exit from safe-mode, and tried restarting the services. its all starting fine. Any suggestions. Thanks in advance Muthu Error log : 2018-09-05 12:04:03,445 - Retrying after 10 seconds. Reason:
