附着到一个已经存在的Yarn Session

Use the following command to start a session

bin/yarn-session.sh

This command will show you the following overview:

Usage:
   Required
     -id,--applicationId  YARN application Id

As already mentioned, YARN_CONF_DIR or HADOOP_CONF_DIR environment variable must be set to read the YARN and HDFS configuration.

Example: application_1463870264508_0029:

./bin/yarn-session.sh -id application_1463870264508_0029

Attaching to a running session uses YARN ResourceManager to determine Job Manager RPC port. Stop the YARN session by stopping the unix process (using CTRL+C) or by entering ‘stop’ into the client.

Submit Job to Flink

Use the following command to submit a Flink program to the YARN cluster:

bin/flink

./bin/flink run ./examples/batch/WordCount.jar \
        hdfs:///..../LICENSE-2.0.txt hdfs:///.../wordcount-result.txt

Run a single Flink job on YARN

The documentation above describes how to start a Flink cluster within a Hadoop YARN environment. It is also possible to launch Flink within YARN only for executing a single job.

Please note that the client then expects the -yn value to be set (number of TaskManagers).

Example:

./bin/flink run -m yarn-cluster -yn 2 ./examples/batch/WordCount.jar

The command line options of the YARN session are also available with the ./bin/flink tool. They are prefixed with a y or yarn (for the long argument options).
