Configure Accumulo Clients
How to configure Accumulo clients when enabling SSL for Accumulo.
To configure Accumulo clients, use
$HOME/.accumulo/config. This is a
simple Java properties file: each line is a configuration, key, and value separated by a
space, and lines beginning with a # symbol are ignored. For example, if we generated a
certificate and placed it in a keystore (as described above), we would generate the
following file for the Accumulo client.
instance.rpc.ssl.enabled true rpc.javax.net.ssl.keyStore /path/to/client-keystore.jks rpc.javax.net.ssl.keyStorePassword client-password rpc.javax.net.ssl.trustStore /path/to/truststore.jks rpc.javax.net.ssl.trustStorePassword truststore-password
When creating a ZooKeeperInstance, the implementation will automatically look for this configuration file and set up a connection with the methods defined in this file. The ClientConfiguration class also contains methods that can be used instead of a configuration file on the file system. Again, the paths to the keystore and truststore are on the local file system, not HDFS.
