-------------------------------------------------------

Commit 62f6a300a5c092a6c61c91fe1546014eb8787b6e in kudu's branch refs/heads/master from Volodymyr Verovkin
[ https://gitbox.apache.org/repos/asf?p=kudu.git;h=62f6a30 ]

[KUDU-2632] Add a DATE type backed by INT32 (Part 2, Java client)

This adds a new DATE type, represented by an INT32 and that should
store the number of days from the Unix epoch, January 1, 1970.

Range:
from
LocalDate.parse("0001-01-01").toEpochDay()
to
LocalDate.parse("9999-12-31").toEpochDay()

Range validation is done in DateUtil::checkDateWithinRange() function.

> {{DATE}} is a timezone-agnostic measure of the current date (without time of day) in YYYY-MM-DD form. The range of values typically supported is 0000-01-01 to 9999-12-31. [Parquet has implemented|https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#date] {{DATE}} as a logical type mapped to int32, represented as the number of days since the start of the UNIX epoch (i.e. January 1, 1970).
> Support for {{DATE}} is currently being added to Impala; we should also add support for it to Kudu.
