warning

JDK 8u271 and JDK 8u281 may cause socket leak issues due to JDK-8245417 and JDK-8256818. Pay attention to the build version of your JDK because some later builds are fixed as described in JDK-8256818.

Workaround: Consider using a more recent version of the JDK like 8u282, or builds of the JDK where the issue is fixed.
JDK 8u40, 8u45, and 8u60 are not supported due to JDK issues impacting CDH functionality:
- JDK 8u40 and 8u45 are affected by JDK-8077155, which affects HTTP authentication for certain web UIs.
- JDK 8u60 is incompatible with the AWS SDK, and causes problem with DistCP. For more information, see the KB article.
Oozie Workflow Graph Display in Hue does not work properly with JDK versions lower than 8u40.
