How To Use

This project helps you to use the D4M Accumulo schema by providing methods to create the needed Accumulo tables. This work is done by the TableManager object. The code below shows how the object is used.

MiniAccumuloConfigImpl miniAccumuloConfig = new MiniAccumuloConfigImpl(new File("/accumulo"), "password");
miniAccumuloConfig.setNumTservers(20);

MiniAccumuloClusterImpl accumulo = new MiniAccumuloClusterImpl(miniAccumuloConfig);
accumulo.start();

Connector connector = accumulo.getConnector("root", "password");

TableManager tableManager = new TableManager(connector, tableOperations);
tableManager.createTables();
tableManager.addSplitsForSha1();
