Discuss the challenges and considerations when using SparkTrials for parallelizing hyperparameter tuning. What are some potential issues that might arise, and how can they be addressed? Provide examples of scenarios where SparkTrials might not be the best choice for parallelization.

Simulated

SparkTrials is always the best choice for parallelizing hyperparameter tuning and has no challenges or limitations.

2.3%

Using SparkTrials can lead to issues such as resource contention and communication overhead, which can be addressed through careful configuration and monitoring.

88.4%

SparkTrials is only used for parallelizing hyperparameter tuning of distributed models, not single-node models.

9.3%

SparkTrials is not suitable for hyperparameter tuning and should be avoided.
