----------------------------------------------------------------

[~rkanter] There are many java doc error, may be more than 250+. I used this simple command to get the number:

{noformat}
$ java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

$ mvn clean javadoc:javadoc -DskipTests  | grep "warning: no description for" | wc -l
     266
{noformat}

The ideal solution would be to fix the java doc, but that is bigger task and I guess we can achieve it slowly with time.

For fixing the issue we can mark the {{failOnError}} to {{false}} into {{maven-javadoc-plugin}} plugin.

Attaching a patch with this fix, Please let me know if this makes sense to you. Thanks.

> While looking at another issue, I came across this. When I cloned latest oozie and tried to build distro using `./bin/mkdistro.sh` I found that the build failed with following error. 
> -------
> ....
> .../oozie/core/src/main/java/org/apache/oozie/service/UUIDService.java:114: error: reference not found
> [ERROR] * systemId is the value defined in the {@link #CONF_SYSTEM_ID} configuration property.
> ...
> -------
> The error seems to be due to the Java 8 feature (DocLint) that checks for errors in Java Docs strictly. The solution would be create a Java 8 specific profile to pass '-Xdoclint:none' to deactivate it. Having this flag for older java version fails to it has to be only for Java 8 using specific profile.
> I will create a patch for the same.
