      Description

      TestWebHdfsContentLength runs a simple hand-coded HTTP server in a background thread to simulate some WebHDFS server responses. In some environments (notably Windows), I have observed that the test can hang and fail intermittently. The root cause is that the server fails to fully consume the client's input. This causes a mismatch in the TCP conversation state, and ultimately the client side hangs, then aborts after the 60-second socket timeout.

        I'm attaching a patch to fix the problem. I've run with this patch multiple times in multiple environments, and the test failure no longer repros.

        I left a comment in the patch explaining the problem in more detail. I'm pasting it here for convenience:

                  // The second request can be sent with Transfer-Encoding: chunked.
                  // The Java HTTP client tends to split the headers and the chunked
                  // body into separate writes, so the first read above likely only read
                  // the headers.  We must fully consume the input to prevent a hang on
                  // the client side.
        

        TestWebHdfsTimeouts is an example of an existing similar test that already works correctly, because it follows the same strategy of fully consuming the input sent by the client.

        I just realized that this test suite has no timeout. I'd like to take the opportunity to add a timeout, so here is patch v002.

        To be fair, with the split into hadoop-hdfs-client, this was only running a small and quick subset of the tests. I'll take it though.

        Sorry for the late. The fix looks good to me. I only have one question: The content read from the new while loop if any could overwrite the header read earlier.
        Should we append them to a StringBuffer and return the full content or it does not matter for the test?

        while (client.getInputStream().read(buf) > 0);

        Hi Xiaoyu. Thank you for reviewing.

        Technically, it's not necessary to retain the full contents of the client request, because the tests only run assertions related to the header information, which is in the first buffer read. However, I still think your suggestion is helpful for the sake of making the code more intuitive. I have attached patch v003.
