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 > (Cloudera)PM:12:00 - 12:55 Lunch Break (Provided by > Cloudera)------------------------------------------------1:00 - > 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, > preemption, larger container, etc. We will also go through YARN upgrade in > order to adopt new features and talk about the challenges.Speaker: Aihua Xu > (Uber), Prashant Golash (Uber)1:30 - 2:10 One more > talk---------------------------------2:20 - 4:00-----------BoF sessions & > Breakout Sessions & Group discussions: Talk about items like JDK 11 > support, next releases (2.10.0, 3.3.0, etc.), Hadoop on Cloud, etc.4:00: > Reception provided by > Cloudera.==============================================Join Zoom > Meetinghttps://cloudera.zoom.us/j/116816195 > <https://cloudera.zoom.us/j/116816195>*
