Consider a scenario where you are tasked with scaling a machine learning model to handle a dataset that is too large to fit into a single machine's memory. Describe the challenges you might face in distributing this model across multiple nodes and how Spark ML can help address these challenges.
A
The primary challenge is data serialization; Spark ML helps by providing built-in functions for data serialization.
B
The main issue is model convergence; Spark ML assists by optimizing the convergence rate through parallel processing.
C
Key difficulties include data partitioning and synchronization across nodes; Spark ML addresses these by offering robust data partitioning and synchronization mechanisms.
D
There are no significant challenges; Spark ML is designed to handle large datasets without issues.
