Akira AJISAKA commented on HADOOP-11602:
----------------------------------------
bq. This means that we could called setDefault() anywhere we start the
services: NameNode, DataNode, Balancer, etc., or clients FileSystem, or other
tools ToolRunner. I did not test it, but seems to be feasible.
This change seems to be incompatible for user applications. Users might have
applications that rely on the services' default locale. (Apparently it's a bad
practice, however, I've ever seen that.)
bq. I would still try to do it via a utility methods
If we use the utility method, hundreds of line change is still needed.
I'll check the patch for branch-2.

> 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.
