Abhishek Bafna commented on OOZIE-2487:

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

$ 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

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 use the {{maven-javadoc-plugin}} plugin and mark 
the {{failOnError}} to {{false}}.

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

> 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.
