By setting the parent.first.classloader.jars parameter to include the names of the desired jars, for example, test1.jar,test2.jar, certain dependency packages can be loaded by the parent class loader. ● For the built-in JAR file list of Flink 1.15 Jar, obtain information about Flink ...
solutions. At present, the company's core P0 operations are basically dual-link, but only on a single cloud. It is hoped that for these core tasks, a cross-cloud active-active solution can be implemented. When a task on one cloud has a problem, it can be stably switched to another ...
