Daryn Sharp commented on HDFS-3577:
-----------------------------------
bq. The file size was 1MB in the test but the block size was only 1kB.
Therefore, it created a lot of local files and failed with
"java.net.SocketException: Too many open files".
Does this mean there's a fd leak? Or at least a leak during the create
request? If so, is the test at fault?

> If reading a file large enough for which the httpserver running
> webhdfs/httpfs uses chunked transfer encoding (more than 24K in the case of
> webhdfs), then the WebHdfsFileSystem client fails with an IOException with
> message *Content-Length header is missing*.
> It looks like WebHdfsFileSystem is delegating opening of the inputstream to
> *ByteRangeInputStream.URLOpener* class, which checks for the *Content-Length*
> header, but when using chunked transfer encoding the *Content-Length* header
> is not present and the *URLOpener.openInputStream()* method thrown an
> exception.
