>
> 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
