public void test_LATEST_TIMESTAMP_isReplaced()
                                      throws Exception

Test that HFileOutputFormat2 RecordWriter amends timestamps if passed a keyvalue whose timestamp is HConstants.LATEST_TIMESTAMP.

Throws:

testMRIncrementalLoad

                           throws Exception

Throws:

Exception

testMRIncrementalLoadWithSplit

public void testMRIncrementalLoadWithSplit()
                                    throws Exception

Exception

testMRIncrementalLoadWithLocality

public void testMRIncrementalLoadWithLocality()
                                       throws Exception

Test for HFileOutputFormat2.LOCALITY_SENSITIVE_CONF_KEY = true This test could only check the correctness of original logic if LOCALITY_SENSITIVE_CONF_KEY is set to true. Because MiniHBaseCluster always run with single hostname (and different ports), it's not possible to check the region locality by comparing region locations and DN hostnames. When MiniHBaseCluster supports explicit hostnames parameter (just like MiniDFSCluster does), we could test region locality features more easily.

Throws:

Exception
