> String#toLowerCase()/toUpperCase() without a locale argument can occur unexpected behavior
based on the locale. It's written in [Javadoc|http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#toLowerCase()]:
> {quote}
> For instance, "TITLE".toLowerCase() in a Turkish locale returns "t\u0131tle", where '\u0131'
is the LATIN SMALL LETTER DOTLESS I character
> {quote}
> This issue is derived from HADOOP-10101.
