In Part 1 of the blog, we covered all the prerequisites needed to deploy a CDH cluster on the Microsoft Azure cloud platform. In Part 2, we will cover the resources required on the Azure platform and actually deploy a cluster with Cloudera Director.
Cloudera Director Use Case
Cloudera Director simplifies cluster creation and lessen the time to an operational cluster on the cloud. It’s a great tool for running POCs in your organization.
Learn how to use Cloudera Director, Microsoft Active Directory (AD DS, AD CS, AD DNS), SAMBA, and SSSD to deploy a secure EDH cluster for workloads in the public cloud.
Authenticating users in Apache Hadoop is the first line of security we recommend. Like most, if not all RDBMS, a user is provided with a username and a password to validate their identity. This is a requirement to access any data managed by those systems.
Since the launch of sparklyr, working with Apache Spark in Apache Hadoop has become much easier for R users. sparklyr contains a dplyr interface into Spark and allows users to leverage crucial machine learning algorithms from Spark MLlib and H2O Sparkling Water. This greatly reduces the barrier of entry for R users in adopting Spark as a tool for big data and should go a long way in enabling R workloads to migrate to Hadoop.
Apache Impala (incubating) includes several features that allow you to restrict or allocate resources so as to maximize stability and performance for your Impala workloads. You can limit both CPU and memory resources used by Impala to manage and prioritize jobs on CDH clusters. This blog post describes the techniques a typical Impala deployment can use to manage its resources.
Static Service Pools
Static service pools isolate services from one another, so that a high load on one service has limited impact on other services.
Learn how replication functionality for Apache Hive metadata and consistency benefits from automated HDFS snapshots benefit production environments.
A robust backup solution that is both correct and efficient is necessary for all production data management systems. Backup and Disaster Recovery (BDR) is a Cloudera Manager feature in Cloudera Enterprise that allows for consistent, efficient replication and version management of data in CDH clusters. Cloudera Enterprise BDR can be used for creating efficient incremental backups of HDFS and Hive data from multiple clusters,
