--------------------------------
hi xintong, I reported this problem in user-zh. Thanks for your reply and
attention. I have made some modifications for Flink-yarn, just want to load
external files，eg thrift jar，udf jar etc. The schema of external files are
https and http. In hadoop-3.1-AbstractHttpFileSystem, ~^getStatus()^~ will
return '^~new FileStatus(-1, false, 1, DEFAULT_BLOCK_SIZE, 0, path)~^', the
length is -1. HttpFileSystem and HttpsFileSystem are the subclass of
AbstractHttpFileSystem, the method did not [be @Override.
|mailto:be%C2%A0@Override.%C2%A0]
I think it is not a flink bug. If we want to load http file, an internal
HttpFileSystem will be implemented or a mock FileStatus should be made, whose
length is nonnegative, so maybe we can support negative file length?
> Yarn provided lib does not work with http paths.

> The problem is that, `HttpFileSystem#getFilsStatus` returns file status with

> negative file length.
