      The scope of hadoop-hdfs's dependency on hadoop-hdfs-client has changed from "compile" to "provided". This may affect users who directly consume hadoop-hdfs, which is a private API. These users need to add a new dependency on hadoop-hdfs-client, or better yet, switch from hadoop-hdfs to hadoop-hdfs-client.

      Description

      Mentioned by Allen Wittenauer on HDFS-11356. The hdfs-client jar is in the lib directory rather than with the other hadoop jars:

      From the alpha2 artifacts:

      -> % find . -name "*hdfs-client*.jar"
      ./share/hadoop/httpfs/tomcat/webapps/webhdfs/WEB-INF/lib/hadoop-hdfs-client-3.0.0-alpha2.jar
      ./share/hadoop/hdfs/sources/hadoop-hdfs-client-3.0.0-alpha2-sources.jar
      ./share/hadoop/hdfs/sources/hadoop-hdfs-client-3.0.0-alpha2-test-sources.jar
      ./share/hadoop/hdfs/lib/hadoop-hdfs-client-3.0.0-alpha2.jar
      ./share/hadoop/hdfs/hadoop-hdfs-client-3.0.0-alpha2-tests.jar
      

      Strangely enough, the tests jar is in the right place.

          Upload v1 patch for this JIRA.
          Use hadoop-assemble to generate hadoop-client jar.
          With this patch, the hadoop-client jar is much smaller because the dependency jars are outputed into share/hadoop/hdfs/lib instead of hadoop-client jar.

          Hi Yuanbo Liu thanks for working on this!

          I ran mvn clean package DskipTests -Pdist -Dmaven.javadoc.skip and looked in hadoop-dist/target/hadoop* to test your patch. It looks like the hdfs client jar is still in the lib directory:

          -> % find . -name "hadoop-hdfs-client*.jar"
          ./share/hadoop/hdfs/lib/hadoop-hdfs-client-3.0.0-alpha3-SNAPSHOT.jar
          

          Looks like the source and test jars are also missing.

          Would appreciate if you also tried running HttpFS from a tarball, to make sure it still works okay without the hadoop-hdfs-client JAR in its lib directory.

          With this patch, the hadoop-client jar is much smaller because the dependency jars are outputed into share/hadoop/hdfs/lib instead of hadoop-client jar.

          I didn't see any size difference in the shaded hadoop-client-* or hadoop-hdfs-client jars, could you elaborate on this?

          Thanks for the patch Yuanbo. I'm still thinking about this. The patch basically changes hadoop-hdfs' dependency on hadoop-hdfs-client from compile scope to provided, then fixed up other poms to refer to hadoop-hdfs-client with provided or test scope where needed.

          Overall, it seems okay. Applications shouldn't be depending on hadoop-hdfs directly, so breaking them is okay (possibly good, as a prod to move to the client deps). We also expect Hadoop deps like this to be on the classpath when running Hadoop daemons.

          That said, I am not a Maven expert, or super familiar with the expectations of dist-layout-stitching.

          Steve Loughran, Allen Wittenauer, any comments?

          Andrew Wang Thanks for your review.
          I think it's ok to change the scope since hadoop-3 is not released formally. The root cause is that hadoop-hdfs-client is a compile dependence of hadoop-hdfs. When another project is dependent on hadoop-hdfs, then hadoop-hdfs-client will be considered as a third-party lib and outputted into lib path by hadoop-assembly plugin.
          If changing scope is an unacceptable behavior, then I will think another way to solve this problem.

          I knew we should have stuck with Ant

          I propose we keep this change in trunk and see how alpha3 impacts downstreams. It's theoretically fine for branch-2 too since downstreams shouldn't be using our server-side artifacts, but we all know how that is.

          +1 will commit to trunk shortly.

It's theoretically fine for branch-2 too since downstreams shouldn't be using our server-side artifacts, but we all know how that is. +1 will commit to trunk shortly.

          This broke the ability to run Hadoop from the source tree as documented in the Wiki (https://wiki.apache.org/hadoop/HowToSetupYourDevelopmentEnvironment) as the client dependency is missing from hadoop-hdfs-project/hadoop-hdfs/target/hadoop-hdfs-3.0.0-*/share/hadoop/hdfs/lib.

          I'm not questioning that this is a good change but I wonder how all of you guys are running Hadoop from source these days? We need to update the documentation and/or fix this situation somehow.

          I poked at this some more, and filed HDFS-12197 with a possible solution. The problem is more general, in that the NFS gateway and HTTPFS already didn't work even before this change. It's just that now the NameNode is broken too, and the NN is used a good bit more than the other two
