Hadoop &引用；“内容类型”；用于使用Web HDFS REST客户端上载jars文件

我使用的是Web HDFS REST客户端，我能够上传

.xml

和

.q

文件

代码的有用部分-

CloseableHttpClient httpclient = HttpClients.createDefault();
HttpPut httpPut = new HttpPut(urlString);
httpPut.setHeader("Accept", "application/xml");
httpPut.setHeader("Content-type", "application/xml");
CloseableHttpResponse response = httpclient.execute(httpPut);

我在上传

.jar

时遇到问题。上载的文件已损坏

我应该在“内容类型”和“接受”中设置什么来上传JAR

HttpPut httpPut = new HttpPut(urlString);
httpPut.setEntity(new StringEntity(readFile(fileName)));
httpPut.setHeader("Accept", "binary/octet-stream");
httpPut.setHeader("Content-type", "binary/octet-stream");

使用

二进制/八位字节流

而不是

应用程序/xml
