Always calculate mis-replicated blocks when safe-mode is turned off.
--------------------------------------------------------------------
Key: HADOOP-4610
URL: https://issues.apache.org/jira/browse/HADOOP-4610
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.18.0
Reporter: Konstantin Shvachko
Assignee: Konstantin Shvachko
Fix For: 0.20.0
After HADOOP-4597 there is one last case when mis-replicated blocks are not
processed. It is when the safe-mode {{extension = 0}}.
We should regenerate {{neededReplications}} and {{excessReplicateMap}} whenever
the safe mode is turned off.
