> Modify the partition discovery mechanism, and support inferring of the TIME data type if partition values match to the time pattern *HH:mm:ss[.SSSSSS]*.
> Currently, for the time values like "10:11:12.123" and "23:59:59.1", the inferred type is STRING. For example:
> {code:scala}
> scala> sql("SELECT time'12:00' AS t, 0 as id").write.partitionBy("t").parquet("/Users/maxim.gekk/tmp/time_parquet2")
> scala> spark.read.parquet("/Users/maxim.gekk/tmp/time_parquet2").printSchema()
> root
>  |-- id: integer (nullable = true)
>  |-- t: string (nullable = true)
> {code}
