RegionLocator metaLoc =
TEST_UTIL.getConnection().getRegionLocator(TableName.META_TABLE_NAME);
LOG.info("testMetaAddressChange -- metaLocator says "
+ metaLoc.getRegionLocation(null).getServerName().getServerName());
{noformat}
It now seems the way the test parses meta location and the location returned by
{{RegionLocator}} instance disagree. Maybe {{RegionLocator}} is not looking
specifically for the first replica?

{noformat}
Test looks for meta with
{noformat}
ZooKeeperWatcher zkw = TEST_UTIL.getZooKeeperWatcher();
String baseZNode = conf.get(HConstants.ZOOKEEPER_ZNODE_PARENT,
HConstants.DEFAULT_ZOOKEEPER_ZNODE_PARENT);
String primaryMetaZnode = ZKUtil.joinZNode(baseZNode,
conf.get("zookeeper.znode.metaserver", "meta-region-server"));
{noformat}
while {{ZooKeeperWatcher}} appears to use
{noformat}
str = ZKUtil.joinZNode(baseZNode,
conf.get("zookeeper.znode.metaserver", "meta-region-server") + "-" +
replicaId);
{noformat}
Looking at logic in {{MetaTableLocator}}, it seems to specify a default
replicaId of 1, which means it'll always be going to a {{"-" + replicaId}}
location instead of the bare location used in the test.

> In TestMetaWithReplicas, start and shutdown of mini cluster is done at start
> and end of every test in that class respectively, which makes the test class
> to take more time to complete. Instead we can start and stop the mini cluster
> only once per the class.
