Building and configuring a Hadoop Yarn cluster

Apache Hadoop YARN, an open source distributed resource management and job scheduling technology, one of the core components of Apache Hadoop, is responsible for allocating system resources (computing, storage, and network resources) to various applications running in a Hadoop cluster, and scheduling tasks running on each cluster node.

SuperMap iServer supports running distributed analysis service based on Apache Hadoop YARN computing framework. You can set up a yarn cluster with Kerberos authentication or without Kerberos authentication, and configure it for use in iServer. This section will introduce you in detail:

• How to build a Hadoop Yarn without Kerberos authentication on the computer
• How to build a Hadoop Yarn with Kerberos authentication on the computer
• If you already have a Hadoop Yarn cluster available, you also need to iServer中configure to use Hadoop Yarn cluster in iServer
