elek opened a new pull request #489: HDDS-1115. Provide ozone specific top-level pom.xml
URL: https://github.com/apache/hadoop/pull/489
 
 
   Ozone build process doesn't require the pom.xml in the top level hadoop directory as we use hadoop 3.2 artifacts as parents of hadoop-ozone and hadoop-hdds. The ./pom.xml is used only to include the hadoop-ozone/hadoop-hdds projects in the maven reactor.
   
   From command line, it's easy to build only the ozone artifacts:
   
   {code}
   mvn clean install -Phdds  -am -pl :hadoop-ozone-dist  -Danimal.sniffer.skip=true  -Denforcer.skip=true
   {code}
   
   Where: '-pl' defines the build of the hadoop-ozone-dist project
   and '-am' defines to build all of the dependencies from the source tree (hadoop-ozone-common, hadoop-hdds-common, etc.)
   
   But this filtering is available only from the command line.
   
   With providing a lightweight pom.ozone.xml we can achieve the same:
   
    * We can open only hdds/ozone projects in the IDE/intellij. It makes the development faster as IDE doesn't need to reindex all the sources all the time + it's easy to execute checkstyle/findbugs plugins of the intellij to the whole project.
    * Longer term we should create an ozone specific source artifact (currently the source artifact for hadoop and ozone releases are the same) which also requires a simplified pom.
   
   In this patch I also added the .mvn directory to the .gitignore file.
   
   With 
   {code}
   mkdir -p .mvn && echo "-f ozone.pom.xml" > .mvn/maven.config" you can persist the usage of the ozone.pom.xml for all the subsequent builds (in the same dir)
   
   How to test?
   
   Just do a 'mvn -f ozonze.pom.xml clean install -DskipTests'
