Example 6 with TableExistsException

use of org.apache.accumulo.core.client.TableExistsException in project incubator-rya by apache.

the class PcjTables method createPcjTable.

/**
 * Create a new PCJ table within an Accumulo instance for a SPARQL query.
 * For example, calling the function like this:
 * <pre>
 * PcjTables.createPcjTable(
 *     accumuloConn,
 *
 *     "foo_INDEX_query1234",
 *
 *     Sets.newHashSet(
 *         new VariableOrder("city;worker;customer"),

 *         new VariableOrder("customer;city;worker")),

 *            "?customer &lt;http://talksTo> ?worker. " +

 *            "?worker &lt;http://worksAt> &lt;http://Home>. " +
 *     "}");
 * </pre>

 * @param sparql - The query this table's results solves. (not null)
 * @throws PCJStorageException Could not create a new PCJ table either because Accumulo
