    Description

      When nodemanager links are accessed through YARNUI service, it requires the host and port to be appended in the URI , something like:

      https://host:8443/gateway/sandbox/yarn/nodemanager/node/containerlogs/container_e02_1498543212255_0001_01_000001/user?host=nm-host&port=8042
      

      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:

      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
      
      

      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

      href=/syslog
      

      gets transformed to

      https://host:8443/gateway/sandbox/yarn/nodemanager/node/containerlogs/container_e02_1498543212255_0001_01_000001/user/syslog
      
      

      whereas it should have been transformed to

      https://host:8443/gateway/sandbox/yarn/nodemanager/node/containerlogs/container_e02_1498543212255_0001_01_000001/user/syslog?host=nm-host&port=8042
      

      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.
