在使用命令行界面将Flink作业提交到Yarn中时，如何获取应用程序ID？

Question

my team is building a flink based realtime computation platform. We submit flink job to Yarn. We create a Process and run commit command use CLI. In order to get yarn application id, we create a thread and parse process output. Application id is used in other methods.

For example, we submit job by this command:

nohup flink run  -m yarn-cluster -d -yqu root.default 
-ynm BDP_RTC_FLINK_10457_MultiOutputTestFrontEnd -yjm 1024 
-yn 2 -ytm 1024 -ys 2 

The output is shown below:

2018-10-10 11:21:04 [info] 2018-10-10 11:21:04,629 INFO  org.apache.flink.yarn.AbstractYarnClusterDescriptor           - Submitting application master application_1536669298614_67675
2018-10-10 11:21:04 [info] 2018-10-10 11:21:04,654 INFO  org.apache.hadoop.yarn.client.api.impl.YarnClientImpl         - Submitted application application_1536669298614_67675
2018-10-10 11:21:04 [info] 2018-10-10 11:21:04,656 INFO  org.apache.flink.yarn.AbstractYarnClusterDescriptor           - Deploying cluster, current state ACCEPTED
2018-10-10 11:21:12 [info] 2018-10-10 11:21:12,699 INFO  org.apache.flink.yarn.AbstractYarnClusterDescriptor           - YARN application has been deployed successfully.
2018-10-10 11:21:12 [info] 2018-10-10 11:21:12,700 INFO  org.apache.flink.yarn.AbstractYarnClusterDescriptor           - The Flink YARN client has been started in detached mode.

We parse process output and get application id: application_1536669298614_67675 .

Are there any other elegant solutions to get application id in our situation?

Answer 1

Maybe you can get the relation between the yarn application and the flink job.

Firstly, list the yarn application.

yarn application -list

Then, you get the application list, and you can list flink job on the yarn application.

./bin/flink list -m yarn-cluster -yid <Yarn Application Id>

By the way, you can use

./bin/flink run -d

not use

nohup
