testOneRegionTable

@Test
public void testOneRegionTable(org.junit.jupiter.api.TestInfo testInfo)
                        throws IOException

Just make sure running fixMeta does right thing for the case of a single-region Table where the region gets dropped. There is nothing much we can do. We can't restore what we don't know about (at least from a read of hbase:meta).

Throws:

IOException

makeOverlap

private static org.apache.hadoop.hbase.client.RegionInfo makeOverlap(org.apache.hadoop.hbase.master.MasterServices services,
 org.apache.hadoop.hbase.client.RegionInfo a,
 org.apache.hadoop.hbase.client.RegionInfo b)
                                                              throws IOException

Throws:

IOException

testOverlapCommon

private void testOverlapCommon(org.apache.hadoop.hbase.TableName tn)
                        throws Exception

Throws:

Exception

testOverlap

@Test
public void testOverlap(org.junit.jupiter.api.TestInfo testInfo)
                 throws Exception

Throws:

testMultipleTableOverlaps

@Test
public void testMultipleTableOverlaps()
                               throws Exception

Throws:

testOverlapWithSmallMergeCount

@Test
public void testOverlapWithSmallMergeCount(org.junit.jupiter.api.TestInfo testInfo)
                                    throws Exception

Throws:

testMergeWithMergedChildRegion

@Test
public void testMergeWithMergedChildRegion(org.junit.jupiter.api.TestInfo testInfo)
                                    throws Exception

This test covers the case that one of merged parent regions is a merged child region that has not been GCed but there is no reference files anymore. In this case, it will kick off a GC procedure, but no merge will happen.

Throws:

Exception

testOverlapWithMergeOfNonContiguous

@Test
public void testOverlapWithMergeOfNonContiguous(org.junit.jupiter.api.TestInfo testInfo)
                                         throws Exception

Make it so a big overlap spans many Regions, some of which are non-contiguous. Make it so we can fix this condition. HBASE-24247

Throws:

Exception
