Eli Collins resolved HDFS-243.
------------------------------
Resolution: Duplicate
Closing as a dupe of HDFS-1064 (NN availability), HDFS-1052 (scalability via
multiple NNs).
> Namenode cluster(multi namenode working in active-active mode) to keep high
> availability and expansivity
> --------------------------------------------------------------------------------------------------------
>
> Key: HDFS-243
> URL: https://issues.apache.org/jira/browse/HDFS-243
> 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.
> Reporter: Meng Xu
> Labels: Availability, HA, High
> 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?
