Describe the problem

Hello, folks!

I facing some troubles to train a LightGBM Model. The model fits until a certain point and after that, somehow models stop to train. It is not indicating any kind of error, the model just stop to load and stays in the same place forever. As you can seen below: I've been using features such as: numTasks, numThreads, numBatches, useSingleDatasetMode and useBarrierExecutionMode in order to improve fit performance.

My dataset has about 418 millions lines to train and 18 millions for validation. I've been dealing of with about 21 features, 10 categorical and rest are continuous variables.

DataBricks Cluster Configuration:

--- Single Node
--- 256 GB Ram Memory | 32 Cores

You guys have any idea why I'm having such issue?

Code to reproduce issue

dic_params_reg_model_0 = {'learningRate' : 0.10686341357711826 ,
'featureFraction': 0.9064118023259887,
'maxBin' : 5,
'minDataInLeaf' : 6,
'numIterations' : 53,
'numLeaves' : 147,
'lambdaL2' : 45.405492626469716,
'lambdaL1' : 0.0015480184927416942}

model_cluster_0 = LightGBMRegressor(metric = 'mae', earlyStoppingRound=1, labelCol='target',
dataTransferMode='streaming', numTasks=32, numThreads=32, validationIndicatorCol='validation_col', numBatches=500, useSingleDatasetMode=True, useBarrierExecutionMode=True
).setParams(**dic_params_reg_model_0).fit(train_0)
