I have a simple regression task (using a LightGBMRegressor) where I want to penalize negative predictions more than positive ones. Is there a way to achieve this with the default regression LightGBM objectives (see https://lightgbm.readthedocs.io/en/latest/Parameters.html)? If not, is it somehow possible to define (many example for default LightGBM model) and pass a custom regression objective?

Hello everyone,
Recently I tried to set up petastorm on my company's hadoop cluster.
However as the cluster uses Kerberos for authentication using petastorm failed.
I figured out that petastorm relies on pyarrow which actually supports kerberos authentication.

I hacked "petastorm/petastorm/hdfs/namenode.py" line 250
and replaced it with

driver = 'libhdfs'
return pyarrow.hdfs.c

if they are not class methods then the method would be invoked for every test and a session would be created for each of those tests.

`class PySparkTest(unittest.TestCase):
@classmethod
def suppress_py4j_logging(cls):
logger = logging.getLogger('py4j')
logger.setLevel(logging.WARN)

@classmethod
def create_testing_pyspark_session(cls):
    return Sp
