Hariharan Iyer commented on KNOX-1023:
--------------------------------------
Hi [~smore] - [~vaibhavb] is not with our company any more, so let me take your
questions. The topology file we used was the same as the default sandbox.xml
file. The only change we did was to change the host name for the services to
0.0.0.0, e.g.
{code}
<service>
<role>YARNUI</role>
<url>http://0.0.0.0:8088</url>
</service>
{code}
The cluster is a multiple-node, single-node Hadoop cluster with the following
services running on the master itself:
1. Knox
2. Job History Server
3. And the usual RM, NN, etc
The Node Managers are running on the worker nodes, as usual.
Please let me know if you need any other information.
Thanks,
Hari

> Issue Type: Bug

> When nodemanager links are accessed through YARNUI service, it requires the
> host and port to be appended in the URI , something like:
> {code:java}
> https://host:8443/gateway/sandbox/yarn/nodemanager/node/containerlogs/container_e02_1498543212255_0001_01_000001/user?host=nm-host&port=8042
> {code}
> When I'm coming from the RM page, this link is rendered as an absolute one,
> so the rewrite rule works fine and appends the host and port. However, when
> I'm on the NM page itself, the URLs are not absolute(the URL's on NM page are
> relative), so a different rewrite rule applies:
> {code:java}
> DEBUG hadoop.gateway (UrlRewriteProcessor.java:rewrite(164)) - Rewrote URL:
> /node/containerlogs/container_e01_1498485266952_0006_01_000001/hiyer
> qa3july/stderr/?start=-4096, direction: OUT via implicit rule:
> YARNUI/yarn/outbound/node to URL:
> https://host:8443/gateway/sandbox/yarn/node/containerlogs/container_e01_1498485266952_0006_01_000001/user/stderr
> {code}
> As you can see, this link does not contain the host=nm-host&port=8042 at the
> end of query string, so it does not work. This affects log links for running
> tasks, and links for the nodemanager itself.
> So, the links on NM page of type
> {code:java}
> href=/syslog
> {code}
> gets transformed to
> {code:java}
> https://host:8443/gateway/sandbox/yarn/nodemanager/node/containerlogs/container_e02_1498543212255_0001_01_000001/user/syslog
> {code}
> whereas it should have been transformed to
> {code:java}
> https://host:8443/gateway/sandbox/yarn/nodemanager/node/containerlogs/container_e02_1498543212255_0001_01_000001/user/syslog?host=nm-host&port=8042
> {code}
> One possible solution I could think of is appending the query string of the
> *current* page to the link, but I couldn't see how to do that in a rewrite
> rule.
> Also, if you can provide some code pointers I may look into it. :)
