> Now in hive HadoopFileSystemFactory, we use org.apache.flink.runtime.fs.hdfs.HadoopFileSystem to get FileSystem.
> But it should not work after we setting default child first class loader. Because in standalone mode, the cluster has no hadoop dependency. So the solution is:
>  # Add `flink-hadoop-fs` dependency to hive module, not work, because classes with "org.apache.flink" prefix will always be loaded by parent class loader :(
>  # User add hadoop dependency to standalone cluster, it breaks out-of-the-box.
>  # Shade hadoop FileSystem in hive module, not complex, good.
