> To avoid surprising/wrong results, Hive Query plan shall add an explicit cast over non date/timestamp column type when user try to extract Year/Month/Hour etc..
> This is an example of misleading results.
> {code}
> create table test_base_table(`timecolumn` timestamp, `date_c` string, `timestamp_c` string, `metric_c` double);
> insert into test_base_table values ('2015-03-08 00:00:00', '2015-03-10', '2015-03-08 00:00:00', 5.0);
> CREATE TABLE druid_test_table
> STORED BY 'org.apache.hadoop.hive.druid.DruidStorageHandler'
> TBLPROPERTIES ("druid.segment.granularity" = "DAY")
> AS select
> cast(`timecolumn` as timestamp with local time zone) as `__time`, `date_c`, `timestamp_c`, `metric_c` FROM test_base_table;
> select
> year(date_c), month(date_c),day(date_c), hour(date_c),
> year(timestamp_c), month(timestamp_c),day(timestamp_c), hour(timestamp_c)
> from druid_test_table;
> {code}
> will return the following wrong results:
> {code}
> PREHOOK: query: select
> year(date_c), month(date_c),day(date_c), hour(date_c),
> year(timestamp_c), month(timestamp_c),day(timestamp_c), hour(timestamp_c)
> from druid_test_table
> PREHOOK: type: QUERY
> PREHOOK: Input: default@druid_test_table
> #### A masked pattern was here ####
> POSTHOOK: query: select
> year(date_c), month(date_c),day(date_c), hour(date_c),
> year(timestamp_c), month(timestamp_c),day(timestamp_c), hour(timestamp_c)
> from druid_test_table
