Daryn Sharp commented on HDFS-6965:
-----------------------------------
Simply changing {{node.getRemaining()}} to {{storage.getRemaining()}} is
probably sufficient. Checking both should be redundant, shouldn't it? If the
storage has space, then the node certainly should have space unless there's an
accounting bug.
> NN continues to issue block locations for DNs with full disks

> Key: HDFS-6965
> URL: https://issues.apache.org/jira/browse/HDFS-6965
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.0.0-alpha, 3.0.0
> Reporter: Daryn Sharp
> Assignee: chang li
>
> Encountered issues where DNs have less space than a full block and reject
> incoming transfers. The NN continues giving out locations for these nodes
> for some period of time. It does not appear to be related to the DN's cached
> disk usage.
> One impact is required replications are delayed when a full DN is chosen for
> the pipeline. A DN cannot report a broken pipeline so the replication must
> timeout (5m) before new targets are chosen.
