      Description

      Unlike most RDBMS systems, Impala does not error on most numeric overflow scenarios. Today it can simply return NULL or exhibit C++ like behavior (casting 500 to a TINYINT returns -12). To provide a UX more like RDBMS systems, failing on numeric overflow should be added when using strict_mode (introduced in IMPALA-3579).
