> IMPALA-9182 prints the socket address of the client closing a session or cancelling a query from the WebUI. There is a 'remote_user' field in {{sq_request_info}}. We may be able to print the username when auth is enabled.
> {code:cpp}
> // This structure contains information about the HTTP request.
> struct sq_request_info {
>   const char *request_method; // "GET", "POST", etc
>   const char *uri;            // URL-decoded URI
>   const char *http_version;   // E.g. "1.0", "1.1"
>   const char *query_string;   // URL part after '?', not including '?', or NULL
>   const char *remote_user;    // Authenticated user, or NULL if no auth used
>   long remote_ip;             // Client's IP address
>   int remote_port;            // Client's port
>   int is_ssl;                 // 1 if SSL-ed, 0 if not
>   void *user_data;            // User data pointer passed to sq_start()
>   void *conn_data;            // Connection-specific user data
>   int num_headers;            // Number of HTTP headers
>   struct sq_header {
>     const char *name;         // HTTP header name
>     const char *value;        // HTTP header value
>   } http_headers[64];         // Maximum 64 headers
