Subject Re: Create hashmap using two RDD's
Date Sat, 10 Oct 2015 17:11:33 GMT
Hi Richard,

Requirement is to get latest records using a key i think hash map is a good choice for this
task.
As of now data comes from third party and we are not sure what's the latest record is so hash
map is chosen.
Is there anything better than hash map please let me know.

Thanks
Sri

is really no need to create one at all.  You could just keep everything as RDDs.
