经过调查并在云唐（apache flink用户邮件列表）的协助下
我创建了以下代码
metadatapath—检查点/保存点文件夹中的\u元数据文件的路径
这是在flink 1.6.3版上测试的

DataInputStream in = new DataInputStream(new FileInputStream(metadataPath));
        final Savepoint savepoint = Checkpoints.loadCheckpointMetadata(in, CheckpointTool.class.getClassLoader());

        final Set<String> pathSharedFromMetadata = savepoint.getOperatorStates().stream()
                .flatMap(operatorState -> operatorState.getSubtaskStates().values().stream()
                        .flatMap(operatorSubtaskState -> operatorSubtaskState.getManagedKeyedState().stream()
                                .flatMap(keyedStateHandle -> Stream.concat(((IncrementalKeyedStateHandle) keyedStateHandle).getSharedState().values().stream(),
                                        ((IncrementalKeyedStateHandle) keyedStateHandle).getPrivateState().values().stream())
                                        .map(streamStateHandle -> {
                                            String name = null;
                                            if (streamStateHandle instanceof FileStateHandle) {
                                                name = ((FileStateHandle) streamStateHandle).getFilePath().getName();
                                            } else {
                                                final String handleName = ((ByteStreamStateHandle) streamStateHandle).getHandleName();
                                                name = new File(handleName).getName();
                                            }
                                            return name.trim();

                                        })
                                )
                        )
                )
                .collect(Collectors.toSet());
        System.out.println("pathSharedFromMetadata:" + pathSharedFromMetadata);
