我正在尝试将一个javajar文件上传到httpfs网关后面运行webhdfs的hdfs集群。
我试过这个卷发：

$ curl -v -X PUT --data-binary @myfile.jar "http://myhost:14000/webhdfs/v1/user/myuser/myfile.jar?op=CREATE&user.name=myuser" -H "Content-Type: application/octet-stream"

它似乎起作用了：

* Trying myhost...
* Connected to smyhost (myhost) port 14000 (#0)

> PUT /webhdfs/v1/user/myuser/myfile.jar?op=CREATE&user.name=myuser HTTP/1.1
> Host: myhost:14000
> User-Agent: curl/7.43.0
> Accept: */*
> Content-Type: application/octet-stream
> Content-Length: 2566043
> Expect: 100-continue
> 
< HTTP/1.1 100 Continue

* We are completely uploaded and fine

但在尝试使用jar时，我得到了一个错误：

$ sudo -u myuser hadoop fs -copyToLocal /user/myuser/myfile.jar /home/myuser
$ sudo -u myuser jar -tf /home/myuser/myfile.jar
java.util.zip.ZipException: error in opening zip file
    at java.util.zip.ZipFile.open(Native Method)
    at java.util.zip.ZipFile.<init>(ZipFile.java:215)
    at java.util.zip.ZipFile.<init>(ZipFile.java:145)

    at sun.tools.jar.Main.run(Main.java:245)
    at sun.tools.jar.Main.main(Main.java:1177)

关键是hdfs中jar文件的大小远远大于原始文件，因此怀疑它没有正确上传：

$ ls -la myfile.jar 
-rw-r--r--  1 myuser  myuser  2566043 14 jun 16:11 myfile.jar
$ sudo -u myuser hadoop fs -ls /user/myuser
Found 1 items
-rwxr-xr-x   3 myuser myuser    4620153 2016-06-16 13:10 /user/myuser/myfile.jar

在curl，使用 -T 或者 --data-binary 没什么区别。我在想如果问题出在 Content-Type 头，我试过了 binary/octet-stream . 尽管如此，httpfs还是回来了 HTTP Status 400 - Data upload requests must have content-type set to 'application/octet-stream' .
有什么提示吗？
