Example 1 with RandomVolumeChooser

use of org.apache.accumulo.server.fs.RandomVolumeChooser in project accumulo by apache.

the class VolumeChooserIT method twoTablesRandomVolumeChooser.

// Test that uses two tables with 10 split points each. They each use the RandomVolumeChooser to choose volumes.
@Test
public void twoTablesRandomVolumeChooser() throws Exception {

    // Create namespace
    Connector connector = getConnector();

    // Set properties on the namespace
    connector.namespaceOperations().setProperty(namespace1, PerTableVolumeChooser.TABLE_VOLUME_CHOOSER, RandomVolumeChooser.class.getName());

    addSplits(connector, tableName);
    // Write some data to the table
