ASF GitHub Bot updated HADOOP-20012:
------------------------------------
Labels: pull-request-available (was: )
> YARN - Exclude third-party Jetty and servlet API from the catalog-webapp and
> timelineservice-hbase tests
> --------------------------------------------------------------------------------------------------------
>
> Key: HADOOP-20012
> URL: https://issues.apache.org/jira/browse/HADOOP-20012
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: test, yarn
> Reporter: Jose Luis López
> Priority: Minor
> Labels: pull-request-available
>
> *Scope*:
> * hadoop-yarn-applications-catalog-webapp/pom.xml: on solr-core and
> solr-test-framework, exclude Solr's own Jetty modules and the servlet API:
> jetty-alpn-server, jetty-alpn-java-server, jetty-continuation, jetty-deploy,
> jetty-jmx, jetty-rewrite, jetty-security, jetty-servlets, http2-server and
> javax.servlet:javax.servlet-api.
> * hadoop-yarn-server-timelineservice-hbase-tests/pom.xml: on hbase-server and
> hbase-server:tests (test scope), exclude javax.servlet:javax.servlet-api
> 3.1.0. HBase's shaded Jetty uses the javax.servlet API, which the module
> still gets through hadoop-common: today javax.servlet-api 3.1.0, and
> jetty-servlet-api 4.0.9 after HADOOP-19970. hbase-server-2 already excludes
> it the same way.
> *Why*: the catalog-webapp tests reach Solr only through EmbeddedSolrServer,
> which runs no servlet container. Solr's Jetty (9.4.44) lags Hadoop's managed
> Jetty, so today the module's test classpath holds two Jetty releases. After
> this change only ${jetty.version} is left. hbase-server 2.6.3 is the only
> third-party dependency outside Solr that brings its own servlet API; without
> the exclusion, timelineservice-hbase-tests would keep a second servlet API
> jar after HADOOP-19970.
> *Impact on Jetty 9*: none. All the changed dependencies are test scope, and
> catalog-webapp's main code uses only solrj. In timelineservice-hbase-tests
> the same javax.servlet-api 3.1.0 jar still arrives through hadoop-common
> until HADOOP-19970.
> *Downstream*: none.
> *CI*: two modules.
