System Requirements

This section contains hardware and software requirements for successful installation of Designer Cloud Enterprise Edition.

Platform Node Requirements

Node Installation Requirements

• If it is integrated with a Cloudera cluster, it must be installed on a gateway node that is managed by Cloudera Manager
•  If it is integrated with a Hortonworks cluster, it must be installed on an Ambari/Hadoop client that is managed by Hortonworks Ambari.
  

• If it is integrated with an HDI cluster, it must be installed on an edge node.

• Customers who originally installed an earlier version on a non-edge node will still be supported. If the software is not installed on an edge node, you may be required to copy over files from the cluster and to synchronize these files after upgrades. The cluster upgrade process is more complicated.

• This requirement does not apply to the following cluster integrations:
  • AWS EMR
  • Azure Databricks

Hardware Requirements

Minimum hardware:

Recommended hardware:

Operating System Requirements

The following operating systems are supported for the Alteryx node.

• CentOS 6.4 - 6.x, 7.1, 7.2, 7.4 - 7.6

• RHEL 6.4 - 6.x, 7.1, 7.2, 7.4 - 7.6

• Ubuntu 14.04 (codename Trusty) and 16.04 (codename Xenial)

  NOTE: For Ubuntu installations, some packages must be manually installed. Instructions are provided later in the process.

For more information on RPM dependencies, see System Dependencies.

Database Requirements

The following database versions are supported by the Designer Cloud Powered by Trifacta platform for storing metadata and the user's Wrangle recipes.

Supported versions:

• PostgreSQL 9.6

• MySQL 5.7 Community

  NOTE: If you are installing the databases into MySQL, you must download and install the MySQL Java driver onto the Alteryx node. For more information, see Install Databases for MySQL in the Databases Guide.

  
  

  NOTE: MySQL 5.7 is not supported for installation in Amazon RDS.

For more information on installing and configuring the database, see Install Databases in the Databases Guide.

Other Software Requirements

The following software components must be present.

Java

• Java 1.8

  NOTE: There are additional requirements related to Java JDK listed in the Hadoop Components section listed below.

  NOTE: OpenJDK 1.8 is officially supported. It is installed on the Alteryx node during the installation process.

  NOTE: If you are integrating your Alteryx instance with S3, you must install the Oracle JRE 1.8 onto the Alteryx node. No other version of Java is supported for S3 integration. For more information, see Enable S3 Access in the Configuration Guide.

Other Software

• NginX 1.12.2
• NodeJS 10.13.0

Root User Access

Installation must be executed as the root user on the Alteryx node.

SSL Access

(Optional) If users are connecting to the Designer Cloud Powered by Trifacta platform, an SSL certificate must be created and deployed. See Install SSL Certificate in the Install Guide.

Internet Access

(Optional) Internet access is not required for installation or operation of the platform. However, if the server does not have Internet access, you must acquire additional software as part of the disconnected install. For more information, see Install Dependencies without Internet Access  in the Install Guide.

Hadoop Cluster Requirements

The following requirements apply if you are integrating the Designer Cloud Powered by Trifacta platform with an enterprise Hadoop cluster.

Supported Hadoop Distributions

The Designer Cloud Powered by Trifacta platform supports the following minimum Hadoop distributions.

Cloudera supported distributions

• CDH 6.2 Recommended

• CDH 6.1 

• CDH 6.0
  

  NOTE: CDH 6.x requires that you use the native Spark libraries provided by the cluster. Additional configuration is required. For more information, see Configure for Spark in the Configuration Guide.

• CDH 5.16  Recommended

See Supported Deployment Scenarios for Cloudera in the Install Guide.

Hortonworks supported distributions

• HDP 3.1   Recommended

• HDP 3.0
  
  

  NOTE: HDP 3.x requires that you use the native Spark libraries provided by the cluster. Additional configuration is required. For more information, see Configure for Spark in the Configuration Guide.

• HDP 2.6

See Supported Deployment Scenarios for Hortonworks  in the Install Guide.

EMR supported distributions

See Configure for EMR in the Configuration Guide.

HDInsight supported distributions

See Configure for HDInsight in the Configuration Guide.

Azure Databricks supported distributions

See Configure for Azure Databricks in the Configuration Guide.

Node Requirements

Each cluster node must have the following software:

• Java JDK 1.8 (some exceptions may be listed below)

Hadoop Component Access

The Alteryx deployment must have access to the following.

Java and Spark version requirements

The following matrix identifies the supported versions of Java and Spark on the Hadoop cluster.

Notes:

• Java must be installed on each node of the cluster. For more information, see https://www.cloudera.com/documentation/enterprise/latest/topics/cdh_ig_jdk_installation.html.
• The versions of Java on the Alteryx node and the Hadoop cluster do not have to match.

• If you are integrating with an EMR cluster, there are specific version requirements for EMR. See Configure for Spark in the Configuration Guide.

Other components

• HDFS Namenode

  • WebHDFS

    NOTE: In HDFS, Append Mode must be enabled. See Prepare Hadoop for Integration with the Platform.

    NOTE: If you are enabling high availability failover, you must use HttpFS, instead of WebHDFS. See Enable Integration with Cluster High Availability in the Configuration Guide.

• For YARN:

  • ResourceManager is running.
  • ApplicationMaster's range of ephemeral ports are open to the Alteryx node.
• HiveServer2:
  • HiveServer2 is supported for metadata publishing.
  • WebHCat is not supported.

Hadoop System Ports

For more information, see System Ports.

Site Configuration Files

Hadoop cluster configuration files must be copied into the Alteryx deployment. See Configure for Hadoop in the Configuration Guide.

Security Requirements

• Kerberos supported:
  • If Kerberos is enabled, a keytab file must be accessible to the Designer Cloud Powered by Trifacta platform.
  • See Configure for Kerberos Integration in the Configuration Guide.
• If Kerberos and secure impersonation are not enabled:
  • A user [hadoop.user (default=trifacta)] must be created on each node of the Hadoop cluster.
  • A directory [hadoop.dir (default=trifacta)] must be created on the cluster.
  • The user [hadoop.user] must have full access to the directory. which enables storage of the transformation recipe back into HDFS.
  • See Configure for Hadoop in the Configuration Guide.

Cluster Configuration

For more information on integration with Hadoop, see Prepare Hadoop for Integration with the Platform.

User Requirements

Users must access the Designer Cloud Powered by Trifacta platform through one of the supported browser versions. For more information on user system requirements, see Desktop Requirements.

I/O Requirements
