> Reporter: Chuan Liu

> Fix For: 3.0.0, 2.1.1-beta

> In {{Namenode#copyEditLogSegmentsToSharedDir()}} method, we open a collection
> of EditLogInputStreams to read and apply to shareEditlog. In {{readOpt()}}
> method, we will open the underlying log file on disk. After applying all the
> opts, we do not close the collection of streams currently. This lead to a
> file handle leak on Windows as later we would fail to delete those files.
> This happens in TestInitializeSharedEdits test case, where we explicitly
> called {{Namenode# initializeSharedEdits()}}, where
> {{copyEditLogSegmentsToSharedDir()}} is used. Later we fail to create new
> MiniDFSCluster with the following exception.
> {noformat}
> java.io.IOException: Could not fully delete
