Duo Zhang commented on HBASE-28061:
-----------------------------------
In JVM implementation, the type of return value is also contained in the method
signature, so changing the type will affect the method signature and cause
NoSuchMethodError.
Notice that this happens when you do drop-in replacement, if you recompile your
code then there is no problem.
The only way is to use reflection here...

> Key: HBASE-28061
> URL: https://issues.apache.org/jira/browse/HBASE-28061
> Project: HBase
> Issue Type: Bug
> Components: hadoop3, integration tests
> Reporter: zhangbutao
> Priority: Major
> Attachments: HbaseMiniClusterTest.java, full_output.txt, pom.xml,
> root_cause.png

>
> Note: My test env is *Hadoop3.3.1* & Hbase2.5.5-hadoop3. And if I switch to
> *Hadoop3.1.4* or \{*}Hadoop3.2.4{*}, the test will be ok. I attached the
> source code and pom file.

> I just want to use *HBaseTestingUtility::startMiniHBaseCluster* to launch a
> mini hbase cluster in case of Hadoop.3.3.1, but failed with the following
