[GraphX] Improve LiveJournalPageRank example
1. Removed unnecessary import 2. Modified usage print since user must specify the --numEPart parameter as it is required in Analytics.main Author: Jacky Li <jacky.likun@huawei.com> Closes #4917 from jackylk/import and squashes the following commits: 6c07682 [Jacky Li] fix comment c0df8f2 [Jacky Li] fix scalastyle b6235e6 [Jacky Li] fix for comment 87be83b [Jacky Li] remove default value description 5caae76 [Jacky Li] remove import and modify usage
