Apache Hadoop YARN fs2cs: Converting Fair Scheduler to Capacity Scheduler Benjamin Teke A presentation from ApacheCon 🤍Home 2020 🤍 Apache Hadoop YARN has two popular schedulers, Fair Scheduler and Capacity Scheduler. Although the two are based on different principles, convergent evolution pushed them to be similar both in functionality and the feature set they offer. By now it seems to be a good idea to merge the two or chose one over the other so the entire user base can enjoy one unified support effort and knowledge base. In this talk, we will present our approach which is offering users a way to migrate from Fair Scheduler to Capacity Scheduler by exploring migration paths and filling feature parity gaps. We will also talk about challenges and those aspects of the migration need some engineering effort in order to keep the achievements of fine-tuning Fair Scheduler installations over many years. We will explain why Capacity Scheduler is our scheduler of choice, the way we analyzed differences between the two schedulers, how we found migration paths, and finally, we will present a tool (fs2cs) we developed to help users automate the process. Benjamin is a senior software developer with many years of experience in the presentation of bigdata for the telecom industry (mainly Kafka and HBase). Since early 2020, he has been an integral part of the YARN team at Cloudera. He gained general knowledge in YARN, and recently he started to specialise in Schedulers. He lives in Budapest and besides his interest in photography and cars, he is passionately automatizing his home via IoT.

Next Generation Scheduling YARN and K8s: For Hybrid Cloud/On-prem Environment to run Mixed Workloads

Scheduler of a container orchestration system, such as YARN and K8s, is a critical component that users rely on to plan resources and manage applications. And if we assess where we are today, in YARN effectively it had two power schedulers (Fair and Capacity scheduler) and both serve many strong use cases in big data ecosystem. It can scale up to 50k nodes per cluster, and schedule 20k containers per second, and extremely efficient to manage batch workloads. K8s default scheduler is an industry-proven solution to efficiently manage long-running services. As more big data apps are moving to K8s and cloud world, but many features like hierarchical queues to support multi-tenancy better, fairness resource sharing, and preemption, etc. are either missing or not mature enough at this point of time to support big data apps running on K8s. At this point, there is no solution that exists to address the needs of having a unified resource scheduling experiences across platforms. That makes it extremely difficult to manage workloads running on different environments, from on-premise to cloud. Hence evolving a common scheduler powered from YARN and K8s’s legacy capabilities and improving towards cloud use cases will focus more on use cases like: Better bin-packing scheduling (and gang scheduling) Autoscale up and shrink policy management Effectively run batch workloads and services with clear SLA’s In summary, we are improving core scheduling capabilities to manage both K8s and YARN cluster which is cloud aware as a separate initiative and above-mentioned cases will be the core focus of this initiative. More details of our works will be presented in this talk.

1. FIFO Scheduler : Job Tracker(JT) pull the oldest job first from job queue. It does not consider priority or size of the job. The original scheduling algorithm that was integrated with in the Job Tracker was called FIFO. User can assign priority to job while submission to the cluster. First In First Out is the default scheduling in Hadoop. Advantage: Simple to implement and efficient. Disadvantage: Has no concept of priority or size of job. FIFO is not appropriate for shared clusters. 2. Fair Scheduler : Fair Scheduler assign resources to jobs such that all jobs get on average, an equal share of resources over the time. If there is single job running then that job uses the entire cluster. Fair scheduler can limit the number of concurrent running jobs per user and per pool. mapred-site.xml: lessthan property greaterthan lessthan name greaterthan mapred.jobtracker.taskscheduler lessthan /name greaterthan lessthan value greaterthan org.apache.hadoop.mapred.FairScheduler lessthan /value greaterthan lessthan /property greaterthan 3. Capacity Scheduler : Its used to designed for sharing large cluster, while giving each organization a minimum capacity guarantee. The central idea is that the available resources in Hadoop Map-Reduce cluster are partitioned among multiple organizations who collectively fund the cluster based on computing needs. Benefit is that an organization can access any excess capacity number being used by others. This provides elasticity for the organizations in a cost-effective manner. Job Scheduling Question & Answer: Question -1: What is the default scheduler in Hadoop? Answer: FIFO scheduler is the default scheduler in Hadoop. Question -2: What is the difference between fair scheduler and capacity scheduler? Answer: Fair Scheduler assign resources such as that all jobs get an average, equal share of resources over the time. Capacity scheduler jobs can not use the extra resources. Its designed to sharing a large cluster while giving each organization a minimum capacity guarantee. Note: Replace lessthan and greaterthan text with lessthan and greaterthan symbol.

YARN is the architectural centre of Hadoop that allows multiple data processing engines such as interactive SQL, real-time streaming, data science and batch processing to handle data stored in a single platform, unlocking an entirely new approach to analytics. YARN is the foundation of the new generation of Hadoop and is enabling organizations everywhere to realize a modern data architecture. WHAT YARN DOES: YARN is the prerequisite for Enterprise Hadoop, providing resource management and a central platform to deliver consistent operations, security, and data governance tools across Hadoop clusters. YARN also extends the power of Hadoop to incumbent and new technologies found within the data centre so that they can take advantage of cost effective, linear-scale storage and processing. It provides ISVs and developers a consistent framework for writing data access applications that run IN Hadoop YARN’s original purpose was to split up the two major responsibilities of the JobTracker/TaskTracker into separate entities: • a global ResourceManager • a per-application ApplicationMaster • a per-node slave NodeManager • a per-application Container running on a NodeManager The ResourceManager and the NodeManager formed the new generic system for managing applications in a distributed manner. The ResourceManager is the ultimate authority that arbitrates resources among all applications in the system. The ApplicationMaster is a framework-specific entity that negotiates resources from the ResourceManager and works with the NodeManager(s) to execute and monitor the component tasks. The ResourceManager has a scheduler, which is responsible for allocating resources to the various applications running in the cluster, according to constraints such as queue capacities and user limits. The scheduler schedules based on the resource requirements of each application. Each ApplicationMaster has responsibility for negotiating appropriate resource containers from the scheduler, tracking their status, and monitoring their progress. From the system perspective, the ApplicationMaster runs as a normal container. The NodeManager is the per-machine slave, which is responsible for launching the applications’ containers, monitoring their resource usage (cpu, memory, disk, network) and reporting the same to the ResourceManager.
