public void testIsIndexExists() throws Exception {
    FileShare testData = new FileShare();
    testData.setId(URIUtil.createId(FileShare.class));
    testData.setPath("path1");
    testData.setMountPath("mountPath1");
    getDbClient().createObject(testData);
    ColumnFamily<String, IndexColumnName> indexCF = new ColumnFamily<String, IndexColumnName>("AltIdIndex", StringSerializer.get(), IndexColumnNameSerializer.get());
    Keyspace keyspace = ((DbClientImpl) getDbClient()).getLocalContext().getKeyspace();
    CompositeRangeBuilder builder = IndexColumnNameSerializer.get().buildRange();
    builder.withPrefix("FileShare").greaterThanEquals(testData.getId().toString()).lessThanEquals(testData.getId().toString());
    Rows<String, IndexColumnName> result = keyspace.prepareQuery(indexCF).getAllRows().withColumnRange(builder).execute().getResult();
    for (Row<String, IndexColumnName> row : result) {
        System.out.println(row.getColumns().getColumnByIndex(0).getName());
        assertTrue(helper.isIndexExists(keyspace, indexCF, row.getKey(), row.getColumns().getColumnByIndex(0).getName()));

        assertFalse(helper.isIndexExists(keyspace, indexCF, row.getKey(), row.getColumns().getColumnByIndex(0).getName()));
    }
