stack updated HBASE-2961:
-------------------------
Attachment: 2961-v3.txt
{code}
Make it so zk shutdown is clean. Did it by making each server have
its own Configuration and hence its own HConnection instance, then
in each server (and client) added HCM.deleteConnection on way out. This
runs clean up of the HConnection.. Added to HConnection#close the shutdown
of zk.
Did other refactor while in here; removed crazy ServerConnection and
ServerConnectionManager stuff substituting new RootRegionTracker in its
place.
Tried to fix outstanding tests. One still failing.
M src/test/java/org/apache/hadoop/hbase/TestMultiParallel.java
Up retries for now to make tests pass. Needs rewrite.
M src/test/java/org/apache/hadoop/hbase/regionserver/TestFSErrorsExposed.java
Make a new Configuration so the setting of less tries has an effect
and we don't retry for ever and fail the test.
M src/test/java/org/apache/hadoop/hbase/catalog/TestMetaReaderEditor.java
Minor formatting.
M src/test/java/org/apache/hadoop/hbase/client/TestFromClientSide.java
Reuse predefined variable.
M src/test/java/org/apache/hadoop/hbase/client/TestHCM.java
Renamed of TableServers to HCI
M src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
Removed ServerConnection. Use HConnection.
Use RootRegionTracker to keep tabs on root location.
Add logging of zk sessionid to help w/ debug
M src/main/java/org/apache/hadoop/hbase/regionserver/wal/HLog.java
Minor formatting.
M
src/main/java/org/apache/hadoop/hbase/regionserver/wal/SequenceFileLogReader.java
Need to preserve EOF if thats what we got.
M src/main/java/org/apache/hadoop/hbase/LocalHBaseCluster.java
Minor reformatting.
M src/main/java/org/apache/hadoop/hbase/master/ServerManager.java
M src/main/java/org/apache/hadoop/hbase/master/HMaster.java
M src/main/java/org/apache/hadoop/hbase/catalog/CatalogTracker.java
ServerConnection is gone. Use HConnection instead.
M src/main/java/org/apache/hadoop/hbase/client/HConnectionManager.java
Renamed TableServers as HConnectionImplementation
Use RootRegionTracker for figuring root location. Made it so could get
rid of some locateRegion code.
Added clearRegionCache(tableName) override.
M src/main/java/org/apache/hadoop/hbase/client/HConnection.java
Added clearRegionCache(tableName)
M src/main/java/org/apache/hadoop/hbase/client/ServerConnection.java
M src/main/java/org/apache/hadoop/hbase/client/ServerConnectionManager.java
Deleted crazy stuff.
M src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
On delete of table, don't delete connection; connection is more than
just a connection to an individual table.
