run MLN Generator on imdb_Movielens

Current BN database is probably okay

I tried to run FactorBase on imdb_MovieLens database thrice now but it reports out of memory >errorException in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded
at com.mysql.jdbc.MysqlIO.nextRowFast(MysqlIO.java:2145)

Hm, this may be because Java is running out of RAM or the database server is running out of memory. Both can be fixed but in different ways. Here are my suggestions.

Do a web search on the error to get some info on where it comes from . (e.g. does "GC" mean garbage collection) and what common fixes are.

Move to cs-oschulte-03.cs.sfu.ca . This is not as bit as 01 but not as full either. On that server, I'd start with the following databases:

tutorial_Mondial. There is a _BN already, you don't need to rerun FactorBase.
unielwin. Again there is an _BN already.

If those two work, we can add a couple of others if we like. For now we mainly want to make sure we can run Zhensong's code and understand what it does.

I am able to run MLNExporter.jar on tutorial_imdb database in cs-oschulte-01.cs.sfu.ca . I was initially working on cs-oschulte-03.cs.sfu.ca but it is failing here on ArrayOutOfBoundException.
I am looking into the differences in the tables generated in both the servers.

We can come back to the IMDB later, for now I'm happy with two examples.
