Binglin Chang updated HDFS-4263:
--------------------------------

    Resolution: Won't Fix
        Status: Resolved  (was: Patch Available)

SORRY, my mistake, corruptedBlockMap never contains more than one element. 
Though use a HashMap for single element is confusing, and every read() call create a new HashMap may affect performance.

> DFSInputStream.reportCheckSumFailure do not report all corrupted blocks, it seems the code forgets to loop through the corruptedBlockMap.
