[jira] Updated: (HADOOP-1224) "Browse the filesystem" link pointing to a dead data-node

     [ https://issues.apache.org/jira/browse/HADOOP-1224?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Enis Soztutar updated HADOOP-1224:
----------------------------------

    Attachment: DFSBrowsingDeadNode_v1.0.patch

This patch 
1.changes randomDataNode() so that it will skip deadnodes and decommissioned nodes. Starts with a random data node and checks the data nodes sequentially until a live node is found. 
2.changes the return type of the getDatanodeByIndex() from DatanodeInfo to DatanodeDescriptor.

> On the NameNode status web page "Browse the filesystem" link can point to a dead data-node.
> The reason for that is that FSNamesystem.randomDataNode() selects a random node from the
> list of all nodes rather then selecting among alive nodes only.
