> {{TestDFSClientSocketSize}} has two tests that assert that a value that was
> set via {{java.net.Socket#setSendBufferSize}} is equal to the value
> subsequently returned by {{java.net.Socket#getSendBufferSize}}.
> These tests are flaky when we run them. The occasionally fail.
> This is expected behavior, actually, because
> {{Socket#setSendBufferSize()}}[is only a
> hint|https://docs.oracle.com/javase/7/docs/api/java/net/Socket.html#setSendBufferSize(int)].
> (Similar to how the underlying libc {{setsockopt(SO_SNDBUF)}} works).
