Robert Kanter commented on YARN-6625:
-------------------------------------
Two last minor things and then we're good to go:
# The {{isValidUrl}} method can be more simpler/compact - something like this:
{code:java}
private boolean isValidUrl(String url) {
boolean isValid = false;
try {
HttpURLConnection conn =
(HttpURLConnection) new URL(url).openConnection();
conn.connect();
isValid = (conn.getResponseCode() == HttpURLConnection.HTTP_OK);
} catch (Exception e) {
LOG.debug("Failed to connect to " + url + ": " + e.toString());
}
return isValid;
}
{code}
# Remove the * imports from TestAmFilter
> yarn application -list returns a tracking URL for AM that doesn't work in
> secured and HA environment

> Project: Hadoop YARN
> Issue Type: Bug
> Components: amrmproxy
> Affects Versions: 3.0.0-alpha2
> Reporter: Yufei Gu

>
> The tracking URL given at the command line should work secured or not. The
> tracking URLs are like http://node-2.abc.com:47014 and AM web server supposed
> to redirect it to a RM address like this
> http://node-1.abc.com:8088/proxy/application_1494544954891_0002/, but it
> fails to do that because the connection is rejected when AM is talking to RM
> admin service to get HA status.
