Since SPARK-15617 deprecated precision in MulticlassClassificationEvaluator, many ML examples broken.

pyspark.sql.utils.IllegalArgumentException: u'MulticlassClassificationEvaluator_4c3bb1d73d8cc0cedae6 parameter metricName given invalid value precision.'

We should use accuracy to replace precision in these examples.
