Subject Re: java.lang.OutOfMemoryError: GC overhead limit exceeded

My feeling is that you have some kind of leak going on in your mappers or
reducers and that reducing the number of times the jvm is re-used would
improve matters.

GC overhead limit indicates that your (tiny) heap is full and collection is
not reducing that.
