Normally, you'd set up Accumulo to use the HDFS volume in your accumulo-site.xml file for your servers by setting the instance.volumes field (in your case to the value of 'hdfs://haz0-m:8020/accumulo' or similar).
The shell typically connects to either ZooKeeper using client configuration files or command-line options as its entry point. Run it with the '--help' or '-?' options to see the available options. If it has read permission for your accumulo-site.xml file and the Accumulo conf directory where this file is located is on its class path, the shell may fall back to using your hdfs-site.xml or your accumulo-site.xml to try to figure out things using HDFS... but that's mostly a backwards-compatible/legacy mode. It's better if you explicitly specify on the command line the ZK entry point. On Thu, Feb 1, 2018 at 10:59 AM Geoffry Roberts <threadedb...@gmail.com> wrote: > Thanks Adam, that worked.
