OutOfMemoryError

[carschno]

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).
Our Hadoop cluster comprises 24 nodes with a total of 504 CPU cores and 1.1TB RAM.
