Hi, I am currently interested in experimenting on Flink over Hadoop YARN. I am documenting from the documentation we have here: https://ci.apache.org/projects/flink/flink-docs-release-0.10/setup/yarn_setup.html <https://ci.apache.org/projects/flink/flink-docs-release-0.10/setup/yarn_setup.html>
There is a subsection Start Flink Session which states the following: A session will start all required Flink services (JobManager and TaskManagers) so that you can submit programs to the cluster. Note that you can run multiple programs per session. Can you be more precise regarding the multiple programs per session? If I submit multiple programs concurently what will happen (can I?)? Maybe they will run in a FIFO fashion or what should I expect? The internals section specify that users can execute multiple Flink Yarn sessions in parallel. This is great, this invites to static partitioning of resources in order to run multiple applications concurrently. Do you support a fair scheduler similar to what Spark claims it has? There is FAQ section (https://ci.apache.org/projects/flink/flink-docs-release-0.10/faq.html <https://ci.apache.org/projects/flink/flink-docs-release-0.10/faq.html>) resource that is missing, can this be updated? Thank you. Best regards, Ovidiu
