Hi,
I'm currently working on the Map Reduce Job History UI rewrite rules, and
found several potential bugs here.
<rewrite template="1; url=/gateway/jobstoryui/jobstory/jobhistory/logs/{**}"
/>
For this rewrite template
<https://github.com/apache/knox/blob/master/gateway-service-definitions/src/main/resources/services/yarnui/2.7.0/rewrite.xml#L104>,
let's not say what the `jobstory` is here for now. I think the target url
should start with something like {$frontend[url]}, just like other OUT
rules, because the previous one doesn't specify the deployment/environment
after word `gateway`.
But after I change it to <rewrite template="1; url={$frontend[url]}/
jobstoryui/jobstory/jobhistory/logs/{**}"/>, the variable {$frontend[url]}
is not replaced with the right value, it's just literal `{$frontend[url]}`
in the target url. And I found that only when the variable following the
double quotes, it can be replaced, otherwise it just stays there as literal
text.
My question is, anyone knows how to fix this bug? Or how to get
{$frontend[url]}
replaced with right value even it's not at the beginning of the template?
Btw, I think the right template should be <rewrite template="1;
url={$frontend[url]}/jobhistory/joblogs/{**}"/>.
Appreciate for any help.
Thanks,
Guang
