Example 96 with ColumnVisibility

use of org.apache.accumulo.core.security.ColumnVisibility in project accumulo by apache.

the class ScanIdIT method generateSampleData.

/**
 * Generate some sample data using random row id to distribute across splits.
 * <p>
 * The primary goal is to determine that each scanner is assigned a unique scan id. This test does check that the count value for fam1 increases if a scanner
 * reads multiple value, but this is secondary consideration for this test, that is included for completeness.
 *
 * @param connector
 *          Accumulo connector Accumulo connector to test cluster or MAC instance.
