Hi,
Wondering if someone could provide advice....
We have CDH 5.9.0 installed and being managed by CM, with a myriad of services configured, installed and running (including Zookeeper, HDFS, YARN, Hue, Hive, HS2, Impala, Sqoop2, HBase, Oozie, Sentry, Solr/Search, Spark and Cloudera Navigator).
When I open a Microsoft IE 11 web browser, point it at the CM URL (port 7180) and navigate to:
Cloudera Management Service -> Navigator Metadata Server -> Cloudera Navigator (from the top menu choice)
and try and open the Cloudera Navigator Server URL (https://{management_node}:7187/login) in a new IE browser tab, I receive a blank screen.
I have read the following Community Support posts:
http://community.cloudera.com/t5/Data-Discovery-Optimization/Cloudera-Navigator-Blank-Page-on-Intern...
And have enable the IE 11 "Enterprise Mode" using this URL (it was originally disabled in the IE 11 broswer):
https://answers.uillinois.edu/page.php?id=59740
I can now see the "Enterprise Mode" option under the MS IE 11 "Tools" menubar, but I still cannot see any content on the Cloudera Navigator page.
I have executed "tree -a" and "ps -afe" command as follows to show the process tree strcture for Navigator:

I have also confirmed port 7187 is open and listening:
[root@{obfuscated_management_node_name}# netstat -lntup | grep LIST | grep 7187
tcp 0 0 0.0.0.0:7187 0.0.0.0:* LISTEN 15276/java
tcp 0 0 127.0.0.1:19001 0.0.0.0:* LISTEN 7187/python
Please help if you are out there Obi Wan Kenobi !
Thanks,
Damion.
