Java 7 and Java 8 are installed on Teradata Appliance 6 for Hadoop clusters. Java 8 is required for Presto. When setting up the Presto config.json file, you must specify the path of the Java 8 home directory. On Teradata Hadoop 6 clusters, /opt/teradata/jvm64/jdk8 is the path of the Java 8 home directory.

  1. At the root prompt, verify that /opt/teradata/jvm64/jdk8 is the active Java JDK path. echo $JAVA_HOME

    The following should display.

    JAVA_HOME=/opt/teradata/jvm64/jdk8
  2. If the path above does not display, record and use the following for the Java 8 JDK path in the config.json file: /opt/teradata/jvm64/jdk8
