Description

In HDFS-10636, the getDataInputStream method uses the getShareDeleteFileInputStream for windows, but the getMetaDataInputStream does not use this. The following error can happen when a DataNode is trying to update the genstamp on a block in Windows.

DataNode Logs:
Caused by: java.io.IOException: Failed to rename G:\data\hdfs\data\current\BP-1\current\finalized\subdir5\subdir16\blk_1_1.meta to G:\data\hdfs\data\current\BP-1\current\finalized\subdir5\subdir16\blk_1_2.meta due to failure in native rename. 32: The process cannot access the file because it is being used by another process.
