Thanks [~jojochuang] for the review and comments.

The content type check seems only performed when I added extra parameters
data=true ?

I think this is not absolutely right. I debugged the test in my local and found
something interesting. In httpfs, if we don't add parameter {{&data=true}}, the
data stream of uploading file and the relevant attribute parameters
(replication, blocksize, etc.) will be ignored. Instead of, it will create a
new url in {{HttpFSServer#createUploadRedirectionURL}} with adding
{{&data=true}} parameter added then redirect to the new url. Since in new url
the {{data}} was added, it will do the content type check as well . I just test
this in the unit tests, correct me if I am wrong thanks.

I'm absolutely confirm this is right. I debugged the test in my local and found
something interesting. In httpfs, if we don't add parameter {{&data=true}}, the
data stream of uploading file and the relevant attribute parameters
(replication, blocksize, etc.) will be ignored. Instead of, it will create a
new url in {{HttpFSServer#createUploadRedirectionURL}} with {{&data=true}}
parameter added. So the content type checking only happens in data upload
request with sending file data.
