ding created SPARK-15172:
----------------------------
Summary: Warning message should explicitly tell user initial
coefficients is ignored if its size doesn't match expected size in
LogisticRegression
Key: SPARK-15172
URL: https://issues.apache.org/jira/browse/SPARK-15172
Project: Spark
Issue Type: Improvement
Components: ML
Reporter: ding
Priority: Trivial
>From ML/LogisticRegression code logic, if size of initial coefficients doesn't
>match expected size, initial coefficients value will be ignored. We should
>explicitly tell user the information. Besides, log size of initial
>coefficients should be more straightforward than log initial coefficients
>value when size mismatch happened.
