1. Removed unnecessary import
2. Modified usage print since user must specify the --numEPart parameter as it is required in Analytics.main

Are you sure you can remove this one? it imports implicits right?
This change loses the description of the parameter too.
This is on the border of non-trivial, but if it's merely fixing the usage note, seems OK.

[jackylk]

Yes, I think it is OK.
The description of the parameter will be output by the Analytics.Main, looks like:

JackydeMacBook-Pro:spark jackylee$ bin/run-example graphx.LiveJournalPageRank ../data/Wiki-Vote.txt
Set the number of edge partitions using --numEPart.
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
JackydeMacBook-Pro:spark jackylee$ 

[srowen]

Yes, but, why remove the description, which already existed in the help message in this file?

[jackylk]

Yes, you are right. I modified back, just remove the default value description

Eh, but now you have put the option in twice! why not just move it up and remove the square braces to mark it non-optional? keep everything else the same.
