Thanks for submitting this @liupc. The jira description makes sense, though I need to take a closer look at the code to confirm things. But at least two things need to be fixed before this can be merged:

When fetching mapStatuses, IOException is not handled in MapOutputTracker.deserializeMapStatuses which might cause old broadcast not cleaned up. In task retrying, when task was scheduled to the executor where old broadcast was stored, An "Block is already present in the MemoryStore" exception would be thrown.
This PR will clean garbage broadcast when IOException occurred in MetadataFetch to avoid
repeated "Block is already present in the MemoryStore" caused by the uncleaned broadcast garbage
details see: https://issues.apache.org/jira/browse/SPARK-22907
