Keith Turner commented on ACCUMULO-118:
---------------------------------------
Could consider supporting current paths starting with '/' or '../' and absolute
paths like hdfs://NN/abspath. All of these have different prefixes so the code
can easily disambiguate. The upside is that it takes less space in the
metadata table and makes upgrade easier, the downside is that it makes the code
more complex. The complexity can be managed by using centralized code to
decode relative and absolute paths into absolute paths.
> accumulo could work across HDFS instances, which would help it to scale past
> a single namenode

> 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.
