Unit test for detecting corruption of replicas in DFS
-----------------------------------------------------
Key: HADOOP-1249
URL: https://issues.apache.org/jira/browse/HADOOP-1249
Project: Hadoop
Issue Type: Bug
Components: dfs
Reporter: dhruba borthakur
DFS has this important feature that the DFSClient detects corrupted replicas of
a block. We need a unit test that ensures that DFSClient is directed to access
a good copy of a block and ignores corrupted replicas. The existing unit test
named TestFileCorruption does not test this feature.
