2. Configure Accumulo

Accumulo provides example configurations that you can modify. Copy all files from one of the examples folders in /etc/accumulo/conf/examples to /etc/accumulo/conf.
For example, you would use the following command to copy all of the files in the /etc/accumulo/conf/examples/512MB/standalone folder to the /etc/accumulo/conf folder:
```
cp /etc/accumulo/conf/examples/512MB/standalone/* /etc/accumulo/conf
```

Make an Accumulo data directory:

su hdfs
hadoop fs -mkdir -p /user/accumulo/data

Change permissions to restrict access to the data directory to the accumulo user:
```
su hdfs
hadoop fs -chmod -R 700 /user/accumulo/data 
```
Change ownership of the data directory to the Accumulo user and group.
```
su hdfs
hadoop fs -chown -R accumlo:accumulo /user/accumulo/data
```
