Rachid BERKANE commented on AMBARI-14714: ----------------------------------------- [~jluniya] [~sposetti] some design suggestions: one database per cluster: * may simplify cluster move (or configure DB HA for specific cluster) * simplify stacks upgrade dependencies mgmt ... ( different DBs version, ...) * administration delegation: a lightweight ambari may allow to monitor or restart services, + ambari views * attach/detach a cluster from one ambari server to another or install/upgrade ambari independently then attache cluster to new ambari server common/shared database: ambari clusters mgmt * link clusters : storage/compute/data-flow clusters : multi versionned compute clusters may use same storage server * manage hosts and bind ambari agents to specific clusters * migrate a cluster database to elsewere * possibility to manage viewfs/federation config for some clusters (add a hdfs DIR into a second clustes hdfs viewsfs) * replications config * inter-cluster resources federation * mpack repositories management > [Umbrella] Multi Everything Architecture > ---------------------------------------- > > Key: AMBARI-14714 > URL: https://issues.apache.org/jira/browse/AMBARI-14714 > Project: Ambari > Issue Type: Epic > Components: ambari-agent, ambari-server, ambari-upgrade, ambari-web, > stacks > Affects Versions: 2.5.0 > Reporter: Jeff Sposetti > Assignee: Jayush Luniya > Priority: Critical > Labels: pull-request-available > Fix For: 3.0.0 > > Attachments: ApacheAmbariMulti-EverythingArchitecture.pdf > > Time Spent: 9h > Remaining Estimate: 0h > > *Multi Stack Services* (AMBARI-19621) > _Scenario: Deploy HDP & HDF services in same cluster_ > - Deploy HDFS from HDP and Kafka, Storm, NiFI from HDF in the same cluster. > _Scenario: Deploy HDP services from different stack versions in same cluster_ > - Deploy ZK, HDFS, YARN from HDP-2.5, but deploy latest SPARK from HDP-2.6. > *Multiple Service Instances* (AMBARI-20463) > _Scenario: Multi service instances on same version_ > - Cluster includes instance of ZooKeeper vX which is being used by HDFS, YARN. > - User wants to add instance of ZooKeeper vX which is being used by STORM and > KAFKA > _Scenario: Multi service instances on different versions_ > - Cluster includes instance of SPARK vX. > - User wants to add additional instance of SPARK vY. > *Multi Host Component Instances* (AMBARI-20465) > _Scenario: Multi component instances from a service instance on the same host_ > - Single host with 128GB RAM, 16 (actual) Cores, 12*4TB disks. > - Single instance of KAFKA broker is unable to utilize all the resources on > the host. > - User wants to scale up performance by deploying multiple instances of the > KAFKA brokers/host. > *Multi Cluster* (AMBARI-20466) > _Scenario: Manage multiple Hadoop clusters under single Ambari Server_ > - Customer has multiple small Hadoop clusters and would like to manage and > monitor them with a single Ambari Server instance. > *Multi Yarn Hosted Services* (AMBARI-17353) > _Scenario: HBase on YARN_ > - Deploy second instance of HBase as a long running YARN service. > - Manage YARN hosted service similar to traditional hosted services. > - First class support for Yarn hosted services. > _Scenario: Credit Fraud Detection YARN Assembly_ > - YARN Assembly can have its own ZK, KAFKA etc. > - Manage YARN Assemblies as first-class citizen. > *Multi Everything Aware APIs* (AMBARI-19620) > - V2 Ambari Rest API to support Multi Everything Architecture -- This message was sent by Atlassian Jira (v8.3.4#803005)
