ASF subversion and git services commented on ACCUMULO-2061:
-----------------------------------------------------------

Commit 6f0528e5a63851d8de6b014d780a381ab9ed6d62 in accumulo's branch refs/heads/ACCUMULO-2061 from [~elserj]
[ https://git-wip-us.apache.org/repos/asf?p=accumulo.git;h=6f0528e ]

ACCUMULO-2061 Re-sync up the changes from upstream. Start fixing things where it is fit.

Avoiding re-creating the old getFileSystem methods to force us to evaluate
each usage to be aware of whether or not the base path matters.

> {{instance.dfs.uri}} and {{instance.dfs.dir}} are no longer needed with the {{instance.volumes}} property.
> Together, these two fields are needed for upgrades from relative paths, but full URIs for volumes should be specified in the {{instance.volumes}} set.
> Instead of appending {{instance.dfs.dir}} to every volume, which is a bit confusing, they should be specified explicitly in the {{instance.volumes}}.
> Example:
> {code}
>  <property>
>     <name>instance.volumes</name>
>     <value>hdfs://nn1/accumulo</value>
>   </property>
> {code}
> should be equivalent to
> {code}
>  <property>
>     <name>instance.dfs.uri</name>
>     <value>hdfs://nn1</value>
>   </property>
>  <property>
>     <name>instance.dfs.dir</name>
>     <value>/accumulo</value>
>   </property>
> {code}
> This change simplifies the semantics of configuring volumes for Accumulo to use for storage, and is a bit more obvious that we're logically configuring filesystem volumes, not "namenode URIs".
