> HADOOP - Declare jetty-http where it is imported, and drop Jetty's Log and 
> context cast

>                 Key: HADOOP-20016
>                 URL: https://issues.apache.org/jira/browse/HADOOP-20016
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: mapreduce
>            Reporter: Jose Luis López

>            Priority: Minor

> *Scope*:
> * hadoop-project/pom.xml: manage jetty-http at ${jetty.version}. It is not 
> managed today.
> * hadoop-mapreduce-client-shuffle/pom.xml: ShuffleChannelHandler imports 
> org.eclipse.jetty.http.HttpHeader. Declare org.eclipse.jetty:jetty-http, 
> optional.
> * hadoop-common/pom.xml: HttpServer2 and McpHttpServer import 
> org.eclipse.jetty.http.*. Declare jetty-http at compile scope, optional.
> * hadoop-hdfs-httpfs/pom.xml: TestJettyHelper imports 
> org.eclipse.jetty.http.*. Declare jetty-http, optional.
> * hadoop-sls/pom.xml: SLSWebApp imports org.eclipse.jetty.http.*. Declare 
> jetty-http with scope provided, like the module's jetty-server.
> * FSMainOperationsBaseTest, ViewFileSystemTestSetup, ViewFsTestSetup and 
> TestAuthenticationSessionCookie: they logged through 
> org.eclipse.jetty.util.log.Log, which Jetty 10 and later no longer have. Log 
> through SLF4J instead.
> * HttpServer2#inferMimeType: drop the cast to a Jetty context, since 
> ServletContext has getMimeType.
> *Why*: these modules compile against jetty-http that they get only 
> transitively, through jetty-server.
> *Why optional*: it keeps the declaration for compiling each module without 
> passing it on, so what downstream projects resolve does not change. At plain 
> compile scope it did: Maven's nearest-wins mediation picked Hadoop's 
> jetty-http over another one at the same depth, and a project with 
> jetty-client 9.4.40 next to hadoop-common resolved jetty-http 9.4.58 instead 
> of 9.4.40. In the shuffle handler, trunk already resolves jetty-http at 
> compile scope (through the NodeManager and mapreduce-client-common); optional 
> keeps that, whereas provided would change it (review on PR #8699). It is not 
> copied into the mapreduce lib directory.
> *Impact on Jetty 9*: none. jetty-http already resolves at 9.4.58 in each 
> module, and the logging and cast changes behave the same.
> *Downstream*: none. Projects that depend on these modules keep getting 
> jetty-http through jetty-server, as today.
> *CI*: touches hadoop-project, so a full build.
> *PR*: https://github.com/apache/hadoop/pull/8894
