Yang Wang commented on FLINK-20685:
-----------------------------------
It seems that the Flink application is submitted successfully. But the AM(aka
JobManager) could not connect to Yarn ResourceManager. I think you need to
check the classpath of JobManager is correctly set, especially for the
HADOOP_CONF_DIR. I guess not only the Flink jobs but also other workloads on
Yarn could not work too.
If you could share the logs of {{yarn logs -applicationId xxx}}, it will help a
lot.

> Key: FLINK-20685
> URL: https://issues.apache.org/jira/browse/FLINK-20685
> Project: Flink
> Issue Type: Bug
> Components: flink-contrib
> Affects Versions: 1.12.0
> Environment: flink version: 1.12.0
> hadoop version: 3.1.3
> flink shaded hadoop version: flink-shaded-hadoop-3-uber-3.1.1.7.1.1.0

> flink version: 1.12.0
> hadoop version: 3.1.3
> flink shaded hadoop version:
> flink-shaded-hadoop-3-uber-3.1.1.7.1.1.0-565-9.0.jar
> Issue desc: When I start the flink session via script "yarn-session.sh", the
> console log shows " Deployment took more than 60 seconds. Please check if the
> requested resources are available in the YARN cluster". And yarn log shows
> this error "Retrying connect to server: 0.0.0.0/0.0.0.0:8030. Already tried 9
> time(s)", in fact the yarn scheduler address is "hadmaster:9901" in the
> yarn-site.xml for me.
> I am sure that my yarn cluster is running normally because I can run other
> application on yarn succefully and there are enough resources too. I had set
> `YARN_CONF_DIR`, `HADOOP_CONF_DIR`, `HADOOP_CLASSPATH` in system env also.
