> Key: HDFS-14465
> URL: https://issues.apache.org/jira/browse/HDFS-14465
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.9.2
> Reporter: Yicong Cai
> Priority: Major
> Attachments: HDFS-14465.01.patch
>
>
> Scenes:
> There is a small HDFS cluster with 5 DataNodes; one of them is maintained,
> added to the maintenance list, and set
> dfs.namenode.maintenance.replication.min to 1.
> When refresh Nodes, the NameNode starts checking whether the blocks on the
> node require a new replication.
> The replications of the MapReduce task job file is 10 by default,
> isNeededReplicationForMaintenance will determine to false, and
> isSufficientlyReplicated will determine to false, so the block of the job
> file needs to increase the replication.
> When adding a replication, since the cluster has only 5 DataNodes, all the
> nodes have the replications of the block, chooseTargetInOrder will throw a
> NotEnoughReplicasException, so that the replication cannot be increase, and
> the Entering Maintenance cannot be ended.
> This issue will cause the independent small cluster to be unable to use the
> maintenance mode.
>
