Christopher Tubbs reopened ACCUMULO-4640:
-----------------------------------------
Assignee: Christopher Tubbs
I believe I've found the cause of this. It turns out that the SiteConfiguration
was using the client configuration as its parent configuration, when the shell
had already fallen back to the SiteConfiguration because client configuration
didn't have the necessary configuration options.
The client configuration should never be the parent of the SiteConfiguration.
That is the role of the DefaultConfiguration.
This applies to 1.7, 1.8, and 2.0, and may be related to the improvements made
in ACCUMULO-4600 and ACCUMULO-4505
> Accumulo shell is expecting instance.volumes in client.conf instead of
> accumulo-site.xml

> 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.
