of SharedParam
Key: SPARK-17175
URL: https://issues.apache.org/jira/browse/SPARK-17175
Project: Spark
Issue Type: Task
Components: ML
Reporter: Qian Huang
Priority: Minor
It needs to do some investigations and performance tests first, since getting a
formula to determine the aggregation depth is tricky. It could depend on the
memory setting of driver, the dimension of problems, and the number of
partition, etc.
