Are you really sure that all your Cluster Nodes are able to resolve each other with their FQDN?

Looks like some of the DataNode might not be able to resolve the other Node address.


Can you please try pinging each host from other NameNodes & DataNodes with their FQDN to see if they are able to resolve each other properly.


Each cluster node should be able to resolve each other with their FQDN. (please check each hosts FQDN and their /etc/hosts) file if they are same?

.

Ambari File View uses the WebHDFS APIs.

So for testing try to upload files using direct WebHDFS APIs to your HDFS and then see if randomly (Depends on how many datanode you have and their replication factor) you see the same issue sometimes or not?


Following WebHDFS API will try to out your local "/etc/passwd" file to HDFS path "/tmp/passwd.txt" file.

# curl -ivL -X PUT -d@/etc/passwd "http://newhwx1.example.com:50070/webhdfs/v1/tmp/passwd.txt?user.name=admin&op=CREATE"
