Traning MLlib algorithm with yarn-cluster

Hi,

I try to build an Mllib model with yarn-cluster set as master, but the execution fails for both Random Forest and Logistic Regression. Input data is the iris dataset on HDFS.

• yarn-cluster submission works for PySpark script, and master=local model building also works.
• I've only set the master, executor-memory and executor-instances in the Spark config.

The relevant log part:
