Keith Turner commented on ACCUMULO-118:
---------------------------------------
One issue this is trying to solve is overcoming namenode scalability issues.
Before working on this would need to investigate what is being done to make the
namenode more scalable. Would need to decide if we want to contribute to that
work, or spend time working around the issue.
> accumulo could work across HDFS instances, which would help it to scale past
> a single namenode

> Key: ACCUMULO-118
> URL: https://issues.apache.org/jira/browse/ACCUMULO-118
> Project: Accumulo
> Issue Type: Improvement
> Components: master, tserver
> Affects Versions: 1.5.0
> Reporter: Eric Newton
> Assignee: Eric Newton
> Original Estimate: 2,016h
> Remaining Estimate: 2,016h

> Consider using full path names to files, which would allow the servers to
> access the files on any HDFS file system.
> Work may exist elsewhere to run HDFS using a number of NameNode instances to
> break up the namespace.
> We may need a pluggable strategy to determine namespace for new files.
