根据分片上传的API描述，因为对同一个文件需要多个upload的HTTP请求。那么很显然，存在多个RGW负载均衡的场景下，不同的HTTP请求会被负载均衡到不同的RGW上。
那么这是否会导致RGW不能把文件分片正确的合并为一个大文件的问题呢（也就是说 文件分片是否必须被上传到同一个RGW）？
验证步骤：
1. 使用 s3 java sdk 。 TransferManager.upload()方法上传大文件aws-java-sdk-1.11.69.zip
2. 查看nginx access.log 中 http请求的partNumber 分布情况， 确认是否正确负载均衡（测试场境为2个RGW组成负载均衡）
