> Make tree aggregation level in linear/logistic regression configurable
> ----------------------------------------------------------------------

> Key: SPARK-17090
> URL: https://issues.apache.org/jira/browse/SPARK-17090
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Seth Hendrickson
> Priority: Minor
>
> Linear/logistic regression use treeAggregate with default aggregation depth
> for collecting coefficient gradient updates to the driver. For high
> dimensional problems, this can case OOM error on the driver. We should make
> it configurable, perhaps via an expert param, so that users can avoid this
> problem if their data has many features.
