WebMar 19, 2024 · The entry point to the Flink program is an instance of the ExecutionEnvironment class — this defines the context in which a program is executed. Let's create an ExecutionEnvironment to start our processing: ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment (); WebFlink Entry Point . FlinkDataClient is the main entry point for the API. FlinkDataClient is a heavyweight object that needs to be created once, reused and terminated. If you do not terminate this object, the job may never finish and result in exceptions like ClassNotFound.
Flink the program's entry point class

WebTo package the program, simply export all involved classes as a JAR file. The JAR file’s manifest must point to the class that contains the program’s entry point (the class with the public main method). The simplest way to do this is by putting the main-class entry into the manifest (such as main-class: org.apache.flinkexample.MyProgram). WebIn order to run flink in Yarn mode, you need to make the following settings: Set HADOOP_CONF_DIR in flink's interpreter setting or zeppelin-env.sh. Make sure hadoop command is on your PATH. Because internally flink will call command hadoop classpath and load all the hadoop related jars in the flink interpreter process.
WebIf the entry point class implements the org.apache.flink.api.common.Program, then the system calls the getPlan (String...) method to obtain the program plan to execute. If the entry point class does not implement the org.apache.flink.api.common.Program interface, the system will invoke the main method of the class.
