> In at least one place I know of in Hadoop, {{SimpleDateFormatter}} is used to serialize {{Date}} object in a format intended for machine consumption -- and should be following strict formatting rules -- but the {{SimpleDateFormatter}}  instance is not constructed with an explicit {{Locale}} so the platform default is used instead.  This causes things like "Day name in week" ({{E}}) to generate unexpected results depending on the Locale of the machine where the code is running, resulting in date-time strings that violate the formatting rules.
> A specific example of this is {{AuthenticationFilter.createAuthCookie}} which has code that looks like this...
> {code}
>       Date date = new Date(expires);
>       SimpleDateFormat df = new SimpleDateFormat("EEE, " +
>               "dd-MMM-yyyy HH:mm:ss zzz");
>       df.setTimeZone(TimeZone.getTimeZone("GMT"));
>       sb.append("; Expires=").append(df.format(date));
> {code}
> ...which can cause invalid expiration attributes in the {{Set-Cookies}} header like this (as noted by http-commons's {{ResponseProcessCookies}} class...
> {noformat}
> WARN: Invalid cookie header: "Set-Cookie: hadoop.auth=; Path=/; Domain=127.0.0.1; Expires=Ara, 01-Sa-1970 00:00:00 GMT; HttpOnly". Invalid 'expires' attribute: Ara, 01-Sa-1970 00:00:00 GMT
> {noformat}
> There are very likely many other places in the hadoop code base where the default {{Locale}} is being unintentionally used when formatting Dates/Numbers.
