> Key: HDFS-16243
> URL: https://issues.apache.org/jira/browse/HDFS-16243
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode
> Affects Versions: 2.7.2
> Reporter: Hualong Zhang
> Priority: Major
> Fix For: 2.7.2

> Attachments: HDFS-16243.0.patch

>
> When I submitted a task to the hadoop test cluster, it appeared "could only
> be replicated to 0 nodes instead of minReplication (=1)"
> I checked the namenode and datanode logs and did not find any error logs. It
> was not until the use of dfsadmin -report that the available capacity was 0
> and I realized that it may be a configuration problem.
> Checking the configuration found that the value of the
> "dfs.datanode.du.reserved" configuration is greater than the available disk
> space of HDFS, which caused this problem
> It seems that there should be some warnings or errors in the log.
