Akira Ajisaka commented on HADOOP-13852:
----------------------------------------
Note that you need to set {{dfs.namenode.min.supported.datanode.version}} and
{{dfs.datanode.min.supported.namenode.version}} properly to run NameNode and
DataNode daemons. For example, if you build trunk with
{{-Ddeclared.hadoop.version=2.8.0}}, you need to set the two properties to
2.8.0 or lower as well.
> hadoop build to allow hadoop version property to be explicitly set

> Hive (and transitively) Spark, won't start on Hadoop 3.x as the shim layer
> rejects Hadoop v3. As a workaround pending a Hive fix, allow the build to
> have the Hadoop version (currently set to pom.version) to be overridden
> manually.
> This will not affect version names of artifacts, merely the declared Hadoop
> version visible in {{VersionInfo.getVersion()}}
