@ashnee please check hdfs-site.xml and confirm you have valid entries for dfs.namenode.https-address

configuration parameter 'dfs.namenode.https-address' was not found in configurations dictionary!

@gsharma can you share output of below command

#hdfs getconf -confkey "dfs.namenode.https-address"

Output :-

hdfs getconf -confkey "dfs.namenode.https-address"

0.0.0.0:50470

I have changed 0.0.0.0 to hostname in hdfs-site.xml and issue is resolved.
