Hi,
As part of some client work I'm trying to add a service to a Knox topology
in the Hortonworks HDP 2.3.1 sandbox; this includes Knox 0.6.0. My
understanding is that I simply need to add the <service> to the topology
XML and then create directories under <knox home>/data/services with new
service and rewrite XML files.
In this test case the REST service is a similar demo app running on port
8095. I've created the service and rewrite XMLs as before yet the gateway
is throwing a 404 when I try and access the API from outside the sandbox.
The usual calls to WebHDFS through the gateway still work. My demo REST
service is running and can be accessed through curl on the inside of the
gateway.
I've added the following to the default.xml topology (and also
knox-sample.xml, another topology in the HDP sandbox)
<service>
<role>HELLO</role>
<url>http://sandbox.hortonworks.com:8095/greeting</url>
</service>
This is my service.xml in data/services/hello/0.0.1
<service role="HELLO" name="hello" version="0.0.1">
<routes>
<route path="/greeting/v1/?**">
<rewrite apply="HELLO/greeting/inbound/root" to="request.url"/>
</route>
</routes>
</service>
And finally this is my rewrite.xml
<rules>
<rule dir="IN" name="HELLO/greeting/inbound/root"
pattern="*://*:*/**/greeting/v1/?{**}">
<rewrite template="{$serviceUrl[HELLO]}?/v1/{**}"/>
</rule>
</rules>
Am I missing anything in terms of configuration? I must confess I'm not
sure what's going on in rewrite.xml and struggle to get much out of the
documentation.
Best Regards,
Adam
