Jayush Luniya updated AMBARI-14714:
-----------------------------------
Description:
*Multi Stack Services*
Scenario: Deploy HDP & HDF services in same cluster
- Deploy HDFS from HDP and Kafka, Storm, NiFI from HDF in the same cluster.
*Multiple Service Instances*
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*
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*
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*
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.
was:
*Multi Stack Services*
# Scenario: Deploy HDP & HDF services in same cluster
- Deploy HDF services in an HDP cluster (Nifi from HDF, HDFS from HDP stack).
*Multiple Service Instances*
# 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.
# Deploy cluster with multiple instances of a service
#
Provide an ability to handle multiple instances of a Service in a given
cluster. In addition, provide ability for a Stack definition to handle multiple
versions of a given Service (which than can have 0 or more instances in a given
cluster).
