Most probably 10.2 is not fully backwards-compatible with 8.1.7 (clients surely aren't.) Metalink note #132904.1 says that direct export from 8.1.7 and import into 10.2 is not supported. One way to import I can think of is to import the dump into an intermediate 9.2.0.8 database, export from there with 9.2 exp utility and then import this new dump into 10.2. 9.2 is compatible with 8.1.7 and 10.2 is compatible with 9.2 as far as imp/exp are concerned.
Also, make sure both source and target databases (and tools) are at the latest respective patchset levels (8.1.7.4 and 10.2.0.5 or 10.2.0.4, whichever is available for your platform.)
