ConfigurationEdit online Setting up High Availability [HA]This section contains information on how to setup high availability to protect against planned and unplanned events.IBM Storage Scale configuration parameter checklistThe IBM Storage Scale™ checklist shows the parameters that affect the system, the Standard, and Advanced tabs in the Ambari wizard.Dual-network deploymentThis section describes the recommended network configuration for Ambari to manage the Hadoop and IBM Spectrum® Scale cluster if more than one network is configured in the environment. It is recommended to map out how Ambari and IBM Spectrum® Scale network configurations are able to communicate before deploying HDP or IBM Spectrum® Scale in your environment.Manually starting services in AmbariSetting up local repositoryConfiguring LogSearchTo setup LogSearch when IBM Storage Scale™ is integrated in an HDP environment, configuration changes are required to point to the correct NameNode, DataNode and ZKFC logs associated with IBM Storage Scale™. Hadoop Kafka/Zookeeper and IBM Storage Scale Kafka/ZookeeperIBM Storage Scale™ has new audit logging capability, File Audit Logging (FAL) that uses its own libraries for Kafka and zookeeper. In IBM Spectrum® Scale FAL, it will install the Kafka and Zookeeper that were shipped from IBM Storage® Scale.Create Hadoop local directories in IBM Storage ScaleIf you did not create local disks to host the Yarn and Mapreduce local temporary files, and want to use the existing IBM Spectrum® Scale file system, then you need to create directories under IBM Storage® Scale file system for each node.Deploy HDP or IBM Spectrum Scale service on pre-existing IBM Spectrum Scale file systemIf you have one of the following configurations, you can deploy HDP with the IBM Spectrum® Scale service:Deploy FPOIn File Placement Optimizer (FPO) mode, data blocks are stored in chunks in IBM Spectrum® Scale, and replicated to protect against disk and node failure. DFS clients run on the storage node so that they can leverage the data locality for executing the tasks quickly. Hadoop Storage TieringWhen using Hadoop Storage Tiering configuration, the jobs running on the Hadoop cluster with native HDFS can read and write the data from IBM Storage® Scale in real time. Limited Hadoop nodes as IBM Spectrum Scale nodesFor any deployment model, you do not have to put all the Hadoop cluster nodes as GPFS nodes.Configuring multiple file system mount point accessCurrently, the IBM Spectrum® Scale service GUI can support only up to two file systems.Support for Big SQLBig SQL V 6.0.0 is supported from HDP 3.1 with Mpack 2.7.0.3 and HDFS Transparency 3.1.0-1.Parent topic: Cloudera HDP 3.X
