[jira] [Comment Edited] (ACCUMULO-4640) [zookeeper.ZooUtil] ERROR:
unable obtain instance id at hdfs://master:9000/accumulo/instance_id
[ https://issues.apache.org/jira/browse/ACCUMULO-4640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16015945#comment-16015945 ]

-------------------------------------------------------------------
Looking at Shell.java line 508 it appears the volumes are *now* read from the client configuration:
instanceName = clientConfig.get(ClientProperty.INSTANCE_NAME);
Therefore I tried to add the following to client.conf:
instance.volumes=hdfs://master:9000/user/accumulo/accumulo
The shell can now be started. I suppose this is as per design and fully enforced starting from Accumulo 1.8.1.

> 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.
