Akira Ajisaka commented on HADOOP-14284: ---------------------------------------- Thanks [~ozawa] for the very tough work! I tried the v7 patch and {{mvn install -DskipTests}} failed in hadoop-client-check-invariants module: {noformat} [WARNING] Rule 1: org.apache.maven.plugins.enforcer.BanDuplicateClasses failed with message: Duplicate classes found: Found in: org.apache.hadoop:hadoop-client-runtime:jar:3.0.0-alpha3-SNAPSHOT:compile org.apache.hadoop:hadoop-client-api:jar:3.0.0-alpha3-SNAPSHOT:compile {noformat} The failure occurs because both the two module has shaded guava. Would you remove shaded guava from hadoop-client-runtime module? > Shade Guava everywhere > ---------------------- > > Key: HADOOP-14284 > URL: https://issues.apache.org/jira/browse/HADOOP-14284 > Project: Hadoop Common > Issue Type: Bug > Components: build > Affects Versions: 3.0.0-alpha3 > Reporter: Andrew Wang > Assignee: Tsuyoshi Ozawa > Priority: Blocker > Attachments: HADOOP-14238.pre001.patch, HADOOP-14284.002.patch, > HADOOP-14284.004.patch, HADOOP-14284.007.patch > > > HADOOP-10101 upgraded the guava version for 3.x to 21. > Guava is broadly used by Java projects that consume our artifacts. > Unfortunately, these projects also consume our private artifacts like > {{hadoop-hdfs}}. They also are unlikely on the new shaded client introduced > by HADOOP-11804, currently only available in 3.0.0-alpha2. > We should shade Guava everywhere to proactively avoid breaking downstreams. > This isn't a requirement for all dependency upgrades, but it's necessary for > known-bad dependencies like Guava. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
