  <!-- Put your site-specific accumulo configurations here. The available configuration values along with their defaults are documented in docs/config.html Unless
    you are simply testing at your workstation, you will most definitely need to change the three entries below. -->

  <property>
    <name>instance.zookeeper.host</name>
    <value>node1,node2,node3</value>
    <description>comma separated list of zookeeper servers</description>
  </property>

  <property>
    <name>logger.dir.walog</name>
    <value>walogs</value>
    <description>The property only needs to be set if upgrading from 1.4 which used to store write-ahead logs on the local
      filesystem. In 1.5 write-ahead logs are stored in DFS.  When 1.5 is started for the first time it will copy any 1.4
      write ahead logs into DFS.  It is possible to specify a comma-separated list of directories.
    </description>
  </property>

  <property>
    <name>instance.secret</name>
    <value>DEFAULT</value>
    <description>A secret unique to a given instance that all servers must know in order to communicate with one another.
      Change it before initialization. To
      change it later use ./bin/accumulo org.apache.accumulo.server.util.ChangeSecret --old [oldpasswd] --new [newpasswd],
      and then update this file.
