Dongjoon Hyun c59abad052 [SPARK-14402][SQL] initcap UDF doesn't match Hive/Oracle behavior in lowercasing rest of string ... ## What changes were proposed in this pull request? Current, SparkSQL `initCap` is using `toTitleCase` function. However, `UTF8String.toTitleCase` implementation changes only the first letter and just copy the other letters: e.g. sParK --> SParK. This is the correct implementation `toTitleCase`. ``` hive> select initcap('sParK'); Spark ``` ``` scala> sql("select initcap('sParK')").head res0: org.apache.spark.sql.Row = [SParK] ``` This PR updates the implementation of `initcap` using `toLowerCase` and `toTitleCase`. ## How was this patch tested? Pass the Jenkins tests (including new testcase). Author: Dongjoon Hyun <dongjoon@apache.org> Closes #12175 from dongjoon-hyun/SPARK-14402.		2016-04-05 13:31:00 -07:00
