From what I can tell, all of the hdfs and common jars from their respective lib dirs are missing, excluding hadoop-hdfs-client and hadoop-hdfs-nfs. But there are likely more.
Steps to reproduce:
2. mvn install -Pdist,src -Dtar -DskipTests -Pnative
3. ls hadoop-dist/target/hadoop-3.0.0-alpha2-SNAPSHOT/share/hadoop/common
hadoop-nfs-3.0.0-alpha2-SNAPSHOT.jar jdiff lib templates webapps
4. ls hadoop-dist/target/hadoop-3.0.0-alpha2-SNAPSHOT/share/hadoop/hdfs
hadoop-hdfs-nfs-3.0.0-alpha2-SNAPSHOT.jar jdiff lib templates webapps
