In Pyspark, there are two ways to get the count of distinct values. [u'hello world', u'hello pyspark', u'spark context', u'i like spark', u'hadoop rdd', u'text file', u'word count', u'', u''], [u'hello', u'world', u'hello', u'pyspark', u'spark', u'context', u'i', u'like', u'spark', u'hadoop', u'rdd', u'text', u'file', u'word', u'count', u'', u''].
