yunjiong zhao updated HDFS-13441:
---------------------------------
Status: Patch Available (was: Open)
There are two ways to fix this bug: one is making sure NameNode's send new
BlockKey to DataNodes successfully; another one is once DataNode can't find
BlockKey, re-register the Datanode to NameNodes to make sure DataNode get the
newest BlockKeys.
The first way is much more complex and need change more code than second way.
The attached patch is re-register DataNode to NameNodes.
Not tested, just for ideas.
> DataNode missed BlockKey update from NameNode due to HeartbeatResponse was
> dropped
