      Description

      Starting with Accumulo 1.8.1 we are getting the exception as per below when the Accumulo shell is invoked:

      [accumulo@master ~]$ /usr/local/accumulo/bin/accumulo shell -u root -p **removed**
      2017-05-18 14:31:23,667 [zookeeper.ZooUtil] ERROR: unable obtain instance id at hdfs://master:9000/accumulo/instance_id
      2017-05-18 14:31:23,669 [start.Main] ERROR: Thread 'shell' died.
      java.lang.RuntimeException: Accumulo not initialized, there is no instance id at hdfs://master:9000/accumulo/instance_id

      at java.lang.Thread.run(Thread.java:745)

      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-rr- 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.
