Hi team, I downloaded Pinot 0.7.1 and followed the

Manual cluster setup

(link)’s

Using launcher scripts

section, I ran

Copy code

export JAVA_OPTS="-Xms4G -Xmx8G -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCApplicationStoppedTime -XX:+PrintGCApplicationConcurrentTime -Xloggc:gc-pinot-controller.log"
bin/pinot-admin.sh StartController \
    -zkAddress localhost:2191 \
    -controllerPort 9000

to start the controller. However, the controller logs lots of warns like the following (in the thread), and

<http://localhost:9000/>

returns a blank web UI. May I have some help please? Thanks. The docker version works for me but I want to install Pinot on our EC2 nodes for further PoC.

Does curl to controller work?

06/16/2021, 3:28 PM

Yes, curl to controller’s 9000 port works

Mayank

06/16/2021, 3:32 PM

Yeah so I think the cluster is up, not sure about the UI issue.

Kewei Shang

06/16/2021, 3:35 PM

Yeah, I think its an UI issue too. Tried different browsers, all didn’t work. Are these

ClassNotFoundException

WARNs normal?

Mayank

06/16/2021, 3:38 PM

Don’t recall seeing them but if the cluster is up and behaving well, then not sure. Also don’t think that could cause UI issue

Kewei Shang

06/16/2021, 3:55 PM

I can access the http://localhost:9000/#/query page, but not the http://localhost:9000/#/ page (blank)

Mayank

06/16/2021, 3:59 PM

what about help page (swagger)?

Mayank

06/16/2021, 3:59 PM

I have tagged Xiang in case he has seen this issue. If not, perhaps we should file an issue

Kewei Shang

06/16/2021, 4:03 PM

http://localhost:9000/help http://localhost:9000/#/zookeeper http://localhost:9000/#/query all above pages works, only http://localhost:9000/#/ doesn’t work (blank). Sure let’s wait for Xiang’s feedback on it. I can file an issue later if that’s really a bug.

Xiang Fu

06/16/2021, 6:18 PM

I remember the root cause is that ui requires broker/server also up to be shown. It’s fixed recently: https://github.com/apache/incubator-pinot/pull/6935

Xiang Fu

06/16/2021, 6:18 PM

should be fixed in next release

Mayank

06/16/2021, 6:18 PM

Thanks @User

Kewei Shang

06/16/2021, 6:19 PM

Thanks! Indeed, starting broker + server has solved the issue 👍
