### What changes were proposed in this pull request? Database and Table names conform the Hive standard ("[a-zA-z_0-9]+"), i.e. if this name only contains characters, numbers, and _. When calling `toLowerCase` on the names, we should add `Locale.ROOT` to the `toLowerCase`for avoiding inadvertent locale-sensitive variation in behavior (aka the "Turkish locale problem"). ### How was this patch tested? Added a test case Author: Xiao Li <gatorsmile@gmail.com> Closes #17655 from gatorsmile/locale. |
