Cloudera namenode web UI is not launching

Question

I recently installed the CDH distribution of Cloudera 6.1 to create a two node cluster. From the Cloudera Manager UI, all services are running fine.

However the namenode (and datanode) web UI alone is not opening. Firewall is already disabled.

Any pointers on how to debug this problem?

Answer 1

Is anything listening on the ports on the host itself? Did you check namenode logs? They should be in /var/log/hadoop-hdfs/hadoop-cmf-hdfs-NAMENODE-your.server.hostname.com.log.out
