报错4，参考
hive (edu)> select * from ods_cart_info_full limit 1;
FAILED: SemanticException Queries against partitioned tables without a partition filter are disabled for safety reasons. If you know what you are doing, please sethive.strict.checks.large.query to false and that hive.mapred.mode is not set to 'strict' to proceed. Note that if you may get errors or incorrect results if you make a mistake while using some of the unsafe features. No partition predicate for Alias "ods_cart_info_full" Table "ods_cart_info_full"
