Allen Wittenauer updated HDFS-373:
----------------------------------
Labels: newbie (was: )
> Name node should notify administrator if when struggling with replication
> -------------------------------------------------------------------------
>
> Key: HDFS-373
> URL: https://issues.apache.org/jira/browse/HDFS-373
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Robert Chansler
> Assignee: Mac Yang
> Labels: newbie
>
> Name node performance suffers if either the replication queue is to big, or
> the avail space at data nodes is too small. In either case, the administrator
> should be notified.
> If the situation is really desperate, the name node perhaps should enter safe
> mode.
