JDK requirements

BDD requires one of the following JDK versions:

Note: BDD requires a JDK that includes the HotSpot JVM. This will be included in any version you download using the following links, as long as you don't select a version from the JRockit Family.

The JDK must be installed in the same location on all nodes.

Note: If one of the supported JDKs is installed on your Hadoop nodes, you can copy it to your BDD nodes.

Additionally, you must set the $JAVA_HOME environment variable on all nodes. If you have multiple versions of the JDK installed, be sure that this points to the correct one. Additionally, if the path is set to or contains a symlink, the symlink must be identical on all other nodes.
