Juan Yu reassigned HDFS-4324:
-----------------------------
Assignee: Juan Yu
> Track and report out-of-date blocks separately from corrupt blocks
> ------------------------------------------------------------------
>
> Key: HDFS-4324
> URL: https://issues.apache.org/jira/browse/HDFS-4324
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 3.0.0
> Reporter: Todd Lipcon
> Assignee: Juan Yu
>
> Currently in various places (metrics, dfsadmin -report, fsck, logs) we use
> the term "corrupt" to refer to blocks which have an out-of-date generation
> stamp. Since out-of-date blocks are a fairly normal occurrence if a DN
> restarts while data is being written, we should be avoid using 'scary' works
> like _corrupt_. This may need both some textual changes as well as some
> internal changes to count the corruption types distinctly.
