Data Collector Environment Configuration

Data Collector includes several environment variables that you can modify to customize the following areas:

Data Collector directories
User and group used to start Data Collector as a service
Java configuration options
Security Manager that restricts the runtime permissions of user libraries
Path to JAR files to be added to the root classloader
Heap dump creation and file location

Note: Data Collector also includes a SPARK_KAFKA_VERSION environment variable that should not be modified. This variable is used only when you run cluster streaming mode pipelines on a Cloudera CDH cluster. For more information, see Kafka Cluster Requirements.
