> Key: HBASE-23861
> URL: https://issues.apache.org/jira/browse/HBASE-23861
> Project: HBase
> Issue Type: Bug
> Components: dependencies
> Affects Versions: 3.0.0
> Environment: Apache Maven 3.6.1
> Hadoop 3.2.0 and above.
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Major
> Fix For: 3.0.0, 2.3.0
>

> I followed the HBase book
> http://hbase.apache.org/book.html#maven.build.hadoop and wanted to build
> HBase (master) on top of Hadoop 3.2/3.3 but tests failed right away.
> Build:
> {code}
> mvn clean install -Dhadoop.profile=3.0 -Dhadoop-three.version=3.2.1
> -DskipTests
> {code}
> Test:
> {code}
> mvn test -Dtest=TestHelloHBase -Dhadoop.profile=3.0
> -Dhadoop-three.version=3.2.1
> {code}
> {noformat}
> [ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.296
> s <<< FAILURE! - in
> org.apache.hbase.archetypes.exemplars.shaded_client.TestHelloHBase
> [ERROR] org.apache.hbase.archetypes.exemplars.shaded_client.TestHelloHBase

> org.apache.hbase.archetypes.exemplars.shaded_client.TestHelloHBase.beforeClass(TestHelloHBase.java:54)
> {noformat}
> Adding mvn -X parameter, I was able to tell that it was because the
> hbase-server module includes hadoop-distcp and hadoop-dfs-client 3.1.2 (the
> default Hadoop 3 dependency version) while it uses version 3.2.1 of other
> hadoop jars . The classpath conflict (the storage policy satisfier is a new
> feature in Hadoop 3.2) failed the test.
> This is reproducible on any Hadoop version 3.2 and above. It looks to me the
> version of hadoop-distcp and hadoop-hdfs-client should be specified at the
> top level pom (they are specified in hbase-server/pom.xml).
