Remove the directory specified by the instance.dfs.dir property in $ACCUMULO_HOME/conf/accumulo-site.xml from HDFS.

If you did not specify an instance.dfs.dir in accumulo-site.xml, the default is "/accumulo".

You should then be able to call accumulo init with success.

  • Just refresh the page. There's some (bad) static members in the monitor that aren't initialized correctly the first time you visit the page. – elserj Aug 25 '14 at 15:40

I don't have enough rep to answer your follow-up comment.

Make sure you restarted the monitor process since reiniting. Furthermore, make sure the node you're running your monitor on has the same configuration as the rest of the instance, as well as the same configuration for Hadoop on the classpath based on HADOOP_HOME.

  • can you please tell how to restart monitor process? I tried to stop all the processes by using /bin/stop-all.sh but that is not working. – Rajesh Barri Oct 22 '12 at 11:53
  • find the process with ps/jps and just kill it. The only really stateful things are the tservers and that's why we have log recovery. – ohshazbot Nov 02 '12 at 22:39
