-----------------------------------------------------------
After debugging it turns out that the issue was having this in my topology file:
{code}
<provider>
<role>identity-assertion</role>
<name>Default</name>
<enabled>true</enabled>
</provider>
{code}
The identity assertion request wrapper is messing up the query string for the
/jmx/* calls made on the Namenode UI main page. The responses all come back
with empty json instead of failing, so it is even harder to detect.
For example:
https://localhost:8443/gateway/sandbox/hdfs/jmx?qry=Hadoop:service=NameNode,name=NameNodeInfo
becomes this after the identity assertion provider:
http://sandbox.hortonworks.com:50070/jmx?user.name=guest&qry=NameNodeInfo
Disabling the identity-assertion provider eliminates the issue. This is
certainly a bug that needs further investigation.
