Tsuyoshi OZAWA commented on HADOOP-11602:
-----------------------------------------
String#toLowerCase()/toUpperCase() without local 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.
> Fix toUpperCase/toLowerCase to use Locale.ENGLISH
