…local vs cluster srowen thanks for the PR at #10866! sorry it took me a while. This is related to #10866, basically the assignment in the lambda expression in the python example is actually invalid ``` In [1]: data = [1, 2, 3, 4, 5] In [2]: counter = 0 In [3]: rdd = sc.parallelize(data) In [4]: rdd.foreach(lambda x: counter += x) File "<ipython-input-4-fcb86c182bad>", line 1 rdd.foreach(lambda x: counter += x) ^ SyntaxError: invalid syntax ``` Author: Mortada Mehyar <[email protected]> Closes #10867 from mortada/doc_python_fix. (cherry picked from commit 56f57f8) Signed-off-by: Sean Owen <[email protected]>
