-----------------------------------

             Summary: TestWebHdfsContentLength intermittently hangs and fails due to TCP conversation
mismatch between client and server.
                 Key: HDFS-9384
                 URL: https://issues.apache.org/jira/browse/HDFS-9384
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
            Priority: Minor


{{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.
