doTestLogReplay

                      throws Exception

Throws:

testLogReplayWithDistributedLogSplit

public void testLogReplayWithDistributedLogSplit()
                                          throws Exception

Throws:

Exception

getWAL

private org.apache.hadoop.hbase.wal.WAL getWAL(org.apache.hadoop.hbase.regionserver.Region region)

getNumRolledLogFiles

private int getNumRolledLogFiles(org.apache.hadoop.hbase.regionserver.Region region)

testFlushingWhenLogRolling

public void testFlushingWhenLogRolling()
                                throws Exception

When a log roll is about to happen, we do a flush of the regions who will be affected by the log roll. These flushes cannot be a selective flushes, otherwise we cannot roll the logs. This test ensures that we do a full-flush in that scenario.

Throws:

Exception

doPut

private void doPut(org.apache.hadoop.hbase.client.Table table,
 long memstoreFlushSize)
            throws IOException,
InterruptedException

Throws:

IOException

InterruptedException

public void testCompareStoreFileCount()
                               throws Exception

Throws:
