[jira] [Created] (HDFS-3764) Hadoop fsck reports files with blocks
w/o live replicas as corrupt
Eli Collins created HDFS-3764:
---------------------------------
Summary: Hadoop fsck reports files with blocks w/o live replicas as corrupt
Key: HDFS-3764
URL: https://issues.apache.org/jira/browse/HDFS-3764
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.0.0-alpha
Reporter: Eli Collins
fsck calls FSN#listCorruptFileBlocks, this returns info for files where there's no live replicas, which doesn't necessarily indicate the file is "corrupt". Let's make fsck distinguish between:
- Blocks w/o any lives replicas (mostly the case when repl=1 and a DN goes down)
- Blocks where are live replicas are/were corrupt
Perhaps this could leverage the stats from HDFS-2554.
