> Key: HDFS-5020
> URL: https://issues.apache.org/jira/browse/HDFS-5020
> Project: Hadoop HDFS

> Currently DatanodeProtocol#blockReceivedAndDeleted is not idempotent because
> pending replication maps in NN only tracks the number of the pending
> replicas, and a retry request about a received block can cause the pending
> number decreased more than once. We can make blockReceivedAndDeleted
> idempotent by tracking corresponding datanodes in the pending replication
> map.
