Hi,
I run Mr.LDA VariationalInference on a data set with the following basic parameters: 14/07/24 11:43:58 INFO mrlda.VariationalInference: Total number of documents is: 605830 14/07/24 11:43:58 INFO mrlda.VariationalInference: Total number of terms is: 2573070
In Iteration 2, all map jobs fail due to OutOfMemoryError exceptions:

This is re-producibly with varying parameters regarding corpus size, number of mapper, heap size (tried up to 32GB).
