It does seem reasonable to match hive since that was probably the original
intention. I've tagged the JIRA for inclusion in the release notes. A few
comments:
- Update the scala doc to correctly describe the new behavior.
- (existing) it would be great to add an expression description annotation
to InitCap
- (minor) We are now double allocating the byte array. It might be nice
to actually implement this in UTF8String, but we don't have to do this to merge
this PR.
- Is there no way to do title case anymore?
