Advanced settings for connecting to an Amazon EMR cluster

The following advanced settings are also available while you are configuring the Pentaho Server to connect to a working Amazon EMR cluster.

Note: EMR clusters (version 7.x and later) built with JDK 17 exclude the commons-lang-2.6.jar library from their standard Hadoop library directories ($HADOOP_HOME/lib). To use the EMR driver for EMR 7.x, obtain the commons-lang-2.6.jar file from a trusted source, such as the official Maven repository (Maven Repository: commons-lang » commons-lang » 2.6). Then manually copy the downloaded JAR file to the $HADOOP_HOME/lib or $HADOOP_MAPRED_HOME/lib directory on each node within the EMR cluster to ensure that all worker nodes have access to the library.
