> Starting with Accumulo 1.8.1 we are getting the exception as per below when

> The location used to look up the instance_id 
> (hdfs://master:9000/accumulo/instance_id) does not appear to be consistent 
> with this site configuration and I am not quite sure how it is being worked 
> out.
> The Accumulo Overview web page shows that the instance exists:
> Instance ID: 4264f11a-704f-4c1f-880f-08f6154232b2 
> Thu May 18 14:44:03 BST 2017
> The instance_id file is in Hadoop's HDFS:
> [accumulo@master ~]$ /usr/local/hadoop/bin/hdfs dfs -ls 
> /user/accumulo/accumulo/instance_id
> Found 1 items
> -rw-r--r--   3 accumulo supergroup          0 2017-05-18 14:27 
> /user/accumulo/accumulo/instance_id/4264f11a-704f-4c1f-880f-08f6154232b2
> Again, within the same environment as selected above apart for using Accumulo 
> 1.8.0, the shell can be invoked without issues.
> Here's a snippet from accumulo-site.xml:
>   <property>
>     <name>instance.volumes</name>
>     <value>hdfs://master:9000/user/accumulo/accumulo</value>
>     <description>comma separated list of URIs for volumes. example: 
> hdfs://localhost:9000/accumulo</description>
>   </property>
> For historical reasons our "root volume" is not / but /user/accumulo although 
> the above stack trace suggests that / is being used as root volume.
