stack updated HBASE-3074:
-------------------------
Attachment: hbase-3074-part2.txt
Here is part 2 of this fix where I generalize the fix I made for zk to see if
it'll fix other failing tests. In particular TestClusterRestart.
{code}
HConnections go stale if miniCluster is shutdown on them. Make it
so we make new HConnections on other side of a new cluster spin up.
Was cause for failing of last few tests.
M src/test/java/org/apache/hadoop/hbase/HBaseTestingUtility.java
So if you shutdown a cluster and you have HConnections that were
made using the HTUs Configuration, they'll all be stale --
session expired -- and won't be of any use connecting to new cluster
that comes up... now that HConnection is first class dependent on
its own ZooKeeperWatcher instance.
So, I went through this class and fixed it up so we use new
Configurations when could be called either side of a mini cluster
restart. Added note to getConfiguration to be careful what you
do with it because Configuration makes for an HConnection.
M src/test/java/org/apache/hadoop/hbase/TestZooKeeper.java
Don't use same Configuration everywhere.
M src/test/java/org/apache/hadoop/hbase/master/TestRestartCluster.java
Make new Configuration when we make new Cluster so we get fresh
HConnection -- not one w/ stale data, disconnected.
M src/main/java/org/apache/hadoop/hbase/master/ServerManager.java
Check that new server that comes in on a regionServerReport
doesn't have same port and host as one we have already registered
as we do in reportForDuty call (This is preemtive bug fix).
M src/main/java/org/apache/hadoop/hbase/client/HConnectionManager.java
Save of an identifier for HCM and use it in log messages, particularly
when we close -- helps debugging.
M src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
getConfiguration added.
