Overview

This CSD registers Dell PowerScale as a first-class storage service within Cloudera Manager, allowing administrators to configure HDFS-compatible storage backed by a PowerScale cluster.

Key features:

• Integrates PowerScale as an HDFS-compatible storage provider in Cloudera Manager
• Supports Kerberos authentication
• Configures HDFS client settings (short-circuit reads, token service IP handling)
• Gateway role for deploying Hadoop client configuration
• KMS service dependency for encryption support

Building

The CSD is packaged as a JAR file. You can build it using the Cloudera Manager Extensions validator and tooling:

# Clone the Cloudera Manager Extensions tools
git clone https://github.com/cloudera/cm_ext.git
cd cm_ext && mvn install

# Validate the CSD
java -jar validator/target/validator.jar -s descriptor/service.sdl

# Package as JAR
jar cf PowerScale-1.1.0.jar META-INF/ descriptor/ scripts/ images/

Installation

1. Copy the CSD JAR to the Cloudera Manager CSD directory:

   cp PowerScale-1.1.0.jar /opt/cloudera/csd/
   chown cloudera-scm:cloudera-scm /opt/cloudera/csd/PowerScale-1.1.0.jar
