示例1: testCacheSeqNums

import org.apache.hadoop.hbase.HRegionLocation; //导入方法依赖的package包/类
/**
 * Test that stale cache updates don't override newer cached values.
 */
@Test
public void testCacheSeqNums() throws Exception{
  HTable table = TEST_UTIL.createMultiRegionTable(TABLE_NAME2, FAM_NAM);
  Put put = new Put(ROW);
  put.add(FAM_NAM, ROW, ROW);
  table.put(put);
  ConnectionManager.HConnectionImplementation conn =
    (ConnectionManager.HConnectionImplementation)table.getConnection();

  HRegionLocation location = conn.getCachedLocation(TABLE_NAME2, ROW).getRegionLocation();
  assertNotNull(location);

  ServerName anySource = ServerName.valueOf(location.getHostname(), location.getPort() - 1, 0L);

  // Same server as already in cache reporting - overwrites any value despite seqNum.
  int nextPort = location.getPort() + 1;
  conn.updateCachedLocation(location.getRegionInfo(), location.getServerName(),
      ServerName.valueOf("127.0.0.1", nextPort, 0), location.getSeqNum() - 1);
  location = conn.getCachedLocation(TABLE_NAME2, ROW).getRegionLocation();
  Assert.assertEquals(nextPort, location.getPort());

  // No source specified - same.
  nextPort = location.getPort() + 1;
  conn.updateCachedLocation(location.getRegionInfo(), location.getServerName(),
      ServerName.valueOf("127.0.0.1", nextPort, 0), location.getSeqNum() - 1);
  location = conn.getCachedLocation(TABLE_NAME2, ROW).getRegionLocation();
  Assert.assertEquals(nextPort, location.getPort());

  // Higher seqNum - overwrites lower seqNum.
  nextPort = location.getPort() + 1;
  conn.updateCachedLocation(location.getRegionInfo(), anySource,
      ServerName.valueOf("127.0.0.1", nextPort, 0), location.getSeqNum() + 1);
  location = conn.getCachedLocation(TABLE_NAME2, ROW).getRegionLocation();
  Assert.assertEquals(nextPort, location.getPort());

  // Lower seqNum - does not overwrite higher seqNum.
  nextPort = location.getPort() + 1;
  conn.updateCachedLocation(location.getRegionInfo(), anySource,
      ServerName.valueOf("127.0.0.1", nextPort, 0), location.getSeqNum() - 1);
  location = conn.getCachedLocation(TABLE_NAME2, ROW).getRegionLocation();
  Assert.assertEquals(nextPort - 1, location.getPort());
  table.close();
}
