-----------------------------------------------------------------------------------------------------------------------

Key: HDFS-2376
URL: https://issues.apache.org/jira/browse/HDFS-2376
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.20.205.0
Reporter: Arpit Gupta


Here is the issue
1. Find all 3 replicas for a block
2. Corrupt the 3 blocks by overwriting them with smaller content
3. cat the file which had the above block (cat fails as content is not correct)
4. run fsck and fsck still reports the fs as healthy
