拼接元素

Question

我有RDD如下，

>>> rdd.collect() 
[([u'steve'], [u'new', u'york'], [u'baseball']), ([u'smith'], [u'virginia'], [u'football'])] 

我怎樣才能獲得新的RDD爲，

[([u'steve'], [u'newyork'], [u'baseball']), ([u'smith'], [u'virginia'], [u'football'])] 

我想它映射到新RDD與加入，但它不列入工作

Answer 1

我能解決這個問題，

>>> rdd2=rdd.map(lambda l: [''.join(x) for x in l]) 
>>> rdd2.map(tuple).collect() 
[([u'steve'], [u'newyork'], [u'baseball']), ([u'smith'], [u'virginia'], [u'football'])]
