2. Configure Accumulo

Accumulo provides example configurations for you to modify. Copy all files from one of the examples folders from /etc/accumulo/conf/examples/ /standalone to /etc/accumulo/conf and:

  1. Make an Accumulo data directory:

    hadoop fs -mkdir -p /user/accumulo/data 
  2. Change permissions on the data directory to grant access to all users:

    hadoop fs -chmod -R 777 /user/accumulo/data

  3. Change ownership of the data directory to the $ACCUMULO_USER.

    hadoop fs -chown -R $ACCUMULO_USER:$HDFS_USER /user/accumulo/data
