Method Detail

canRunTest

public boolean canRunTest(AccumuloClusterHarness.ClusterType type)

Description copied from class: AccumuloClusterHarness

A test may not be capable of running against a given AccumuloCluster. Implementations can override this method to advertise that they cannot (or perhaps do not) want to run the test.

Overrides:

canRunTest in class AccumuloClusterHarness

testNormalWrite

public void testNormalWrite()
                     throws Exception

This test should succeed.

Throws:

Exception

testClearLocatorAndSplitWrite

public void testClearLocatorAndSplitWrite()
                                   throws Exception

Fixed by ACCUMULO-4229.

This tests a situation that a client which shares a LocatorCache with the tablet server may fall into. Before the problem was fixed, adding a split after the Locator cache falls out of sync caused the BatchWriter to continuously attempt to write to an old, closed tablet. It would do so for 15 seconds until a timeout on the BatchWriter.

Throws:

Exception
