Update Files on the Developer Tool

1. 1. Find hdfs-site.xml and yarn-site.xml on the name node of the cluster.
2. 2. Copy the files to the following location on the machine that hosts the Developer tool: <Informatica installation directory>/clients/DeveloperClient/Hadoop/<Hadoop distribution><version>/conf

yarn-site.xml

yarn.application.classpath

Sets the classpath for YARN applications and enables the Developer tool to read from and write to a highly available cluster.

To identify the classpath, run the yarn classpath command. The following sample text shows a sample classpath entry:

<property>
<name>yarn.application.classpath</name>
<value>
