Spark Language Settings

Spark uses the default locale settings, so if you have a French system installation you must use French menus if if you prefer Spanish ones.

To change the locale one can set the two Java System Properties “user.language” and “user.region”.

See Spark JVM Settings for a general description how to add Java System Properties to Spark and add there

-Duser.language=en

-Duser.region=US

for US English.
