Subject Spark- How can I run MapReduce only on one partition in an RDD?
Date Thu, 13 Nov 2014 22:59:46 GMT
Hi All,

I use textFile to create a RDD. However, I don't want to handle the whole
data in this RDD. For example, maybe I only want to solve the data in 3rd
partition of the RDD.

How can I do it? Here are some possible solutions that I'm thinking:
1. Create multiple RDDs when reading the file
2.  Run MapReduce functions with the specific partition for an RDD.

However, I cannot find any appropriate function.

Thank you and wait for your suggestions.

Best,
Tim
