get rid of destroy since there is a lot of testing based on driver still need the variable. only put in unpersist().
Find it out the hard way.
there is interleaving issue to use unpersist() also.
find out it is due to learning rate issue. both destroy and unpersist() is good to be used. some learning rate will cause worker to learn nothing, the weight become NaN. :(
