Jose Luis López updated HADOOP-20013:
-------------------------------------
    Description: 
*Scope*:
* hadoop-project/pom.xml: on javax-websocket-server-impl, exclude 
javax.annotation:javax.annotation-api, which arrives through jetty-annotations. 
jakarta.annotation-api 1.3.5 already provides the same javax.annotation classes.
* LICENSE-binary: drop javax.annotation:javax.annotation-api, if listed.

*Why*: two jars publish the javax.annotation packages, and which one a module 
sees depends on jar order.

*Impact on Jetty 9*: none. Same classes.

*Downstream*: none for the shaded clients. Direct consumers no longer get 
javax.annotation-api; jakarta.annotation-api provides the same classes.

*CI*: touches hadoop-project, so a full build.

*Scope*:

javax.annotation:javax.annotation-api, which arrives through jetty-annotations. 
jakarta.annotation-api 1.3.5 already provides the same javax.annotation classes.
* hadoop-mapreduce-client-shuffle/pom.xml: ShuffleChannelHandler imports 
org.eclipse.jetty.http.HttpHeader. Declare org.eclipse.jetty:jetty-http.
* hadoop-project/pom.xml: manage jetty-http at ${jetty.version}. It is not 
managed today.
* LICENSE-binary: drop javax.annotation:javax.annotation-api, if listed.

*Why*: two jars publish the javax.annotation packages, and which one a module 
sees depends on jar order. The shuffle compiles against jetty-http that it gets 
only transitively.

*Impact on Jetty 9*: none. Same classes; jetty-http already resolves at 9.4.58.

*Downstream*: none for the shaded clients. Direct consumers no longer get 
javax.annotation-api; jakarta.annotation-api provides the same classes.

*CI*: touches hadoop-project, so a full build.

        Summary: HADOOP - Remove the duplicate javax.annotation-api from the 
classpath  (was: HADOOP - Remove the duplicate javax.annotation-api and declare 
jetty-http in the shuffle)
