{{SparkPipeline#done()}} should consider waiting for all Spark jobs to complete
before shutting down a {{SparkContext}}.
Here is an example that fails
{code}
Pipeline pipeline = new SparkPipeline(sparkConnect, "ParallelAction",
getClass(), getConf());
IdentityFn<Student> fn = IdentityFn.getInstance();
pipeline.read(From.avroFile(input1, Student.class)).parallelDo(fn,
Avros.records(Student.class)).write(To.avroFile(args[3]));
pipeline.runAsync();
pipeline.read(From.avroFile(input2, Student.class)).parallelDo(fn,
Avros.records(Student.class)).write(To.avroFile(args[4]));
pipeline.done();
{code}
Error:
