JDK 8u242 and newer versions cause Site-to-Site failure

When you use JDK 8u242 or a newer version, the RAW transport protocol in Site-to-Site fails with the following exception:
2018-12-19 16:19:26,811 ERROR [Site-to-Site Listener] org.apache.nifi.NiFi
 java.nio.channels.IllegalBlockingModeException: null
 at java.base/sun.nio.ch.ServerSocketAdaptor.accept(ServerSocketAdaptor.java:121)
 at org.apache.nifi.remote.SocketRemoteSiteListener$1.run(SocketRemoteSiteListener.java:125)
 at java.base/java.lang.Thread.run(Thread.java:834)
Workarounds: Choose one of the following options before upgrading to JDK 8u242 or a newer JDK version:
  • Upgrade to HDF 3.5.1 or a newer version. Cloudera recommends this option.
  • Change all the Remote Process Groups and Site-to-Site based reporting tasks to use HTTP transport protocol instead of RAW transport protocol.

If neither of these options work for you, contact Cloudera Support for other options.
