use of org.apache.accumulo.proxy.thrift.Range in project accumulo by apache.

the class TestProxyReadWrite method readWriteOneShotWithRange.

@Test

        if (i % 1000 == 0 || i == maxInserts - 1) {
            tpc.proxy().updateAndFlush(userpass, testtable, mutations);
            mutations.clear();
        }
    }
    Key stop = new Key();
    stop.setRow("5".getBytes());

        i += kvList.getResultsSize();
        hasNext = kvList.isMore();
    }
    assertEquals(i, 50000);
}

Example 4 with Range

use of org.apache.accumulo.proxy.thrift.Range in project accumulo by apache.

the class TestProxyReadWrite method readWriteBatchOneShotWithRange.

/**
