Subject [jira] [Created] (HDFS-7596) NameNode should prune dead storages from storageMap
Date Thu, 08 Jan 2015 23:15:34 GMT
Arpit Agarwal created HDFS-7596:
-----------------------------------

             Summary: NameNode should prune dead storages from storageMap
                 Key: HDFS-7596
                 URL: https://issues.apache.org/jira/browse/HDFS-7596
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.6.0
            Reporter: Arpit Agarwal
            Assignee: Arpit Agarwal


The NameNode must be able to prune storages that are no longer reported by the DataNode and
that have no blocks associated. These stale storages can skew the balancer behavior.

Detailed discussion on HDFS-7575.
