Step 6: Accept JDK License
To allow Cloudera Manager to automatically install the Oracle JDK on cluster hosts, read the JDK license and check the box labeled Install Oracle Java SE Development Kit (JDK8) if you accept the terms. If you installed your own Oracle JDK version, leave the box unchecked.
If you allow Cloudera Manager to install the JDK, a second checkbox appears, labeled Install Java Unlimited Strength Encryption Policy Files. These policy files are required to enable AES-256 encryption in JDK versions lower than 1.8u161. JDK 1.8u161 and higher enable unlimited strength encryption by default, and do not require policy files.
After reading the license terms and checking the applicable boxes, click Continue.
