                 Key: SPARK-21078
                 URL: https://issues.apache.org/jira/browse/SPARK-21078

          Components: Spark Core
    Affects Versions: 2.1.1
            Reporter: fangfengbin


FsHistoryProvider has some threads to mergeApplicationListing.
mergeApplicationListing function has code like this:
applications.synchronized { 
...
applications = mergedApps 
...
} 

applications object is changed,  so the synchronized do not work.
