Hi,
I've installed Apache Knox via Ambari.
Added Ambari service + configured Ldap.
Based on that, I was able to curl webhdfs as specific ldap use.
But when I access Ambari via knox in a Browser I can browse everything, but can't make changes to configuration.
Every time I change some configs in services I get this ajax response:
{
"status" : 400,
"message" : "Invalid Request: Malformed Request Body. An exception occurred parsing the request body: Unexpected character ('%' (code 37)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: java.io.StringReader@3af8ede7; line: 1, column: 3]"
}
When I access it directly, all works as expected.
Worth to mention, that I have nginx on top of knox (I need it for many reasons).
And my basic configuration is as follows:
server {
listen 443 ssl;
server_name gateway.example.com;
ssl_certificate /etc/ssl/cert.crt;
ssl_certificate_key /etc/ssl/cert.key;
location / {
proxy_pass https://knox:8443;
# this magic is needed for WebSocket
proxy_http_version 1.1;
proxy_redirect off;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
}
}
In my browser, I access Ambari like that:
https://gateway.example.com/gateway/default/ambari
Another thing that doesn't work for me regarding this matter is when I set this value:
default.app.topology.name to 'default' (as above url indicates).
I always get 500 error and some weird logs about rewriting.
Happy to provide more info, but not sure what else.
