wanted to target covtype20x with 3 different alpha/lamba combos
there other tests that do random params with covtype20x and covtype200x
this test can run with the config jsons, if you run while in a directory with hosts in in the name..
This will run with 3 jvms on local machine
cd testdir_multi_jvm
python test_GLM_covtype20x_hosts.py

This will run wherever your config json says to
cd testdir_hosts
python ../testdir_multi_jvm/test_GLM_covtype20x_hosts.py

This will run on 172
cd testdir_hosts
python ../testdir_multi_jvm/test_GLM_covtype20x_hosts.py -cj pytest-config_172.json

if run with the hosts behavior, it will also run covtype200x.dat

all the files assume the machine used has /home/0xdiag/datasets
(all the 150-175 machines do)
