@tvmanikandan
we are adding decision tree PMML support for multiclass classification, see
https://issues.apache.org/jira/browse/SPARK-8542.
Linear SVMs supports only binary classification, while logistic regression
supports both binary and multiclass classification problems. If you would like
logistic regression multiclass classification PMML export and the decision tree
is not enough, please create a Jira issue under the
https://issues.apache.org/jira/browse/SPARK-8545 PMML improvement umbrella.
