             Project: Ranger
          Issue Type: Bug
          Components: plugins
    Affects Versions: 0.7.1, 1.0.0

            Priority: Minor


>From the performance and code logic analysis, we should optimize the flush 
>function of HDFSAuditDestination class. The reason is as following:
1. Its logic is not clear. There are duplicate code and repeated judgment.
2. Through my tests, in the case of large data, the log io will have a big 
impact on performance.
