ThinkerLei opened a new pull request, #6456:
URL: https://github.com/apache/hadoop/pull/6456
Now, DataNode will cacheReport to all NameNode when CacheCapacitySize is not
zero. But sometimes, not all NameNodes have CacheBlock on this DataNode. So
BPServiceActor should skip cacheReport when one blockPool does not have
CacheBlock on this DataNode. If so, the NameNode will reduce unnecessary lock
contention
