Specifically, each striped block now consists of multiple data/parity blocks stored in corresponding DataNodes. The current code's calculation is thus inconsistent: each striped block is only counted as 1 expected block, while each of its member block may increase the number of received blocks by 1. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
