Describe the process of integrating Hyperopt with Spark MLlib for hyperparameter tuning. What specific challenges might arise when attempting to parallelize the tuning process across a Spark cluster, and how can these be mitigated?
A
Integrating Hyperopt with Spark MLlib is straightforward and involves no challenges.
B
The main challenge is the incompatibility between Hyperopt and Spark MLlib, which cannot be resolved.
C
Challenges include data serialization and synchronization issues across nodes, which can be mitigated by using efficient data handling techniques and careful configuration of the Spark cluster.
D
Parallelizing the tuning process is not possible with Hyperopt and Spark MLlib.
