8.3. Installing Java 8
The Oracle Java 1.8 JRE (64-bit), update 151 or higher, is a prerequisite for Presto. If a suitable 64-bit version of Oracle Java 8 is already installed on the cluster, you can skip this step.
There are two ways to install Java: via RPM and via tarball. The RPM installation sets the default Java on your machine to be Java 8. If
it is acceptable to set the default Java to be Java 8, you can use
presto-admin to install Java, otherwise you will need to install Java 8 manually.
To install Java via RPM using
Download Oracle Java 8, selecting the Oracle Java 1.8 (64-bit) RPM download for Linux.
Copy the RPM to a location accessible by
Run the following command to install Java 8 on each node in the Presto cluster:
$ ./presto-admin package install <local_path_to_java_rpm>
server-install-label will look for your Oracle Java 1.8 installation at locations where Java is normally installed when using the binary or the RPM based installer. Otherwise, you need to have an environment variable called
JAVA8_HOME set with your Java 1.8 install path. If
JAVA8_HOME is not set or is pointing to an incompatible version of Java, the installer will look for the
JAVA_HOME environment variable for a compatible version of Java. If neither of these environmental variables is set with a compatible version, and
presto-admin fails to find Java 8 at any of the normal installation locations, then
server install will fail. After successfully running
server install you can find the Java being used by Presto at
If you have installed the JDK,
JAVA8_HOME should be set so refer to the
jre subdirectory of the JDK.
If installing Java on SLES, you will need to specify the flag
presto-admin package install, so that the RPM is installed without checking or validating dependencies.
