Review comment:
If `i` reaches the end of `dbVerParts`, means that the hive version is
behind the db version, which supposed to be compatiable. For example,
dbVerParts is `4`, `0`, `0`
hiveVerParts is `4`, `0`, `0`, `alpha`, `1`
the `hiveVerParts.length == dbVerParts.length;` returns false in this case.
