Subject [jira] [Commented] (SPARK-14402) UTF8String.toTitleCase should return non-first letters in lowercase
Date Tue, 05 Apr 2016 09:48:25 GMT

    [ https://issues.apache.org/jira/browse/SPARK-14402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15225985#comment-15225985
] 

Sean Owen commented on SPARK-14402:
-----------------------------------

Oh I see. That's a more specific and probably legit issue. If the intent is to emulate initcap
from Hive then you're right that this doesn't behave the same way, since it explicitly promises
to un-capitalize the rest of the letters. Maybe retitle this?

Are there other usages of toTitleCase? if this is the only one and it's not fit for purpose,
maybe it should be moved out to the code implementing initcap and modified to implement initcap.

> Current `UTF8String.toTitleCase` implementation changes only the first letter and just
copy the other letters: e.g. *sParK* --> *SParK*.
