Subject [jira] [Resolved] (HDFS-243) Namenode cluster(multi namenode working in active-active mode) to keep high availability and expansivity
Date Thu, 21 Apr 2011 17:11:06 GMT

     [ https://issues.apache.org/jira/browse/HDFS-243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eli Collins resolved HDFS-243.
------------------------------

    Resolution: Duplicate

Closing as a dupe of HDFS-1064 (NN availability), HDFS-1052 (scalability via multiple NNs).

>             Project: Hadoop HDFS
>          Issue Type: New Feature
>         Environment: Hadoop cluster on more than thousands of nodes, most of all, the
number of files is mass.

>   Original Estimate: 672h
>  Remaining Estimate: 672h

>  If we use the DFS to store a great quantity of files which is very small, i.e. the namenode
is under high pressure of indexing files, should we consider to introduce other namenodes
working concurrently for availability and scalability?
