> If we have date datatype in mysql, string datatype defined in hive, JdbcStorageHandler
will translate the date to string with the format yyyy-MM-dd HH:mm:ss. However, Hive convention
is yyyy-MM-dd, we shall follow Hive convention. Eg:
> mysql: CREATE TABLE test ("datekey" DATE);
> hive: CREATE TABLE test (datekey string) STORED BY 'org.apache.hive.storage.jdbc.JdbcStorageHandler'
TBLPROPERTIES (......"hive.sql.table" = "test"......);
> Then in hive, do: select datekey from test;
> We get: 1999-03-24 00:00:00
> But should be: 1999-03-24
