Jose Luis López updated HADOOP-20013:
-------------------------------------
Summary: HADOOP - Remove the duplicate javax.annotation-api and declare
jetty-http in the shuffle (was: HADOOP — Remove the duplicate
javax.servlet-api and javax.annotation-api from the classpath)
> HADOOP - Remove the duplicate javax.annotation-api and declare jetty-http in
> the shuffle
> ----------------------------------------------------------------------------------------
>
> Key: HADOOP-20013
> URL: https://issues.apache.org/jira/browse/HADOOP-20013
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: build, common
> Reporter: Jose Luis López
> Priority: Major
>
> *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.
> * 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.
