> 10:15:-------------Talk: Hadoop storage in cloud-native
> environmentsAbstract: Hadoop is a mature storage system but designed years
> before the cloud-native movement. Kubernetes and other cloud-native tools
> are emerging solutions for containerized environments but sometimes they
> require different approaches.In this presentation we would like to share
> our experiences to run Apache Hadoop Ozone in Kubernetes and the connection
> point to other cloud-native ecosystem elements. We will compare the
> benefits and drawbacks to use Kubernetes and Hadoop storage together and
> show our current achievements and future plans.Speaker: Marton Elek
> (Cloudera)10:20 - 11:00:--------------Talk: Selective Wire Encryption In
> HDFSAbstract: Wire data encryption is a key component of the Hadoop
> Distributed File System (HDFS). However, such encryption enforcement comes
> in as an all-or-nothing feature. In our use case at LinkedIn, we would like
> to selectively expose fast unencrypted access to fully managed internal
> clients, which can be trusted, while only expose encrypted access to
> clients outside of the trusted circle with higher security risks. That way
> we minimize performance overhead for trusted internal clients while still
> securing data from potential outside threats. Our design extends HDFS
> NameNode to run on multiple ports, connecting to different NameNode ports
> would end up with different levels of encryption protection. This
> protection then gets enforced for both NameNode RPC and the subsequent data
> transfers to/from DataNode. This approach comes with minimum operational
> and performance overhead.Speaker: Konstantin Shvachko (LinkedIn), Chen
> Liang (LinkedIn)11:10 - 11:55:-------------Talk: YuniKorn: Next Generation
> Scheduling for YARN and K8sAbstract: We will talk about our open source
> work - YuniKorn scheduler project (Y for YARN, K for K8s, uni- for Unified)
> brings long-wanted features such as hierarchical queues, fairness between
> users/jobs/queues, preemption to Kubernetes; and it brings service
> scheduling enhancements to YARN. Any improvements to this scheduler can
> benefit both Kubernetes and YARN community.Speaker: Wangda Tan

> 1:25-----------Talk: Yarn Efficiency at UberAbstract: We will present the
> work done at Uber to improve YARN cluster utilization and job SOA with
> elastic resource management, low compute workload on passive datacenter,

> order to adopt new features and talk about the challenges.Speaker: Aihua Xu
