I have created a instance while initializing accumulo by calling accumulo init But now i want to remove that instance and as well i want to create a new instance. Can any one help to do this?
回答1:
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.

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.
