Jim Kellerman b205cac36d HADOOP-1466 Clean up warnings, visibility and javadoc issues in HBase.
Works in my environment. Since no changes were made to the code aside from white space adjustment, not testing with Hudson.

Jim Kellerman 4fa87a0cbb HADOOP-1528 HClient for multiple tables - expose close table function
HTable

    * added public method close
    * added protected method checkClosed
    * make getConnection public

HConnectionManager

    * a call to getTableServers or reloadTableServers will cause information for closed
      tables to be reloaded

TestHTable

    * new test case

Jim Kellerman 84ef0ba801 HADOOP-1528 HClient for multiple tables (phase 2) all HBase client side code
(except TestHClient and HBaseShell) have been converted to use the new client
side objects (HTable/HBaseAdmin/HConnection) instead of HClient.

HBaseAdmin
- Expose connection methods getMaster, isMasterRunning and listTables

Jim Kellerman 2bbcc5a122 HADOOP-1528 HClient for multiple tables (phase 1)
Modified:

HConstants
static final Text[] COL_REGIONINFO_ARRAY = new Text [] {COL_REGIONINFO};
static final Text EMPTY_START_ROW = new Text();

HMaster
- don't process a region server exit message if the lease has timed
  out. Otherwise we end up with two pending server shutdown messages
  to process and chaos ensues.
- don't reassign the root region when the server's lease expires. The
  lease expiration handler will queue a PendingServerShutdown
  operation that must run before the root region is reassigned because
  the HLog of the dead server must be split before any regions served
  by the dead server are reassigned.
- added some additional debug level logging

HBaseClusterTestCase
- call HConnectionManager.deleteConnection(conf) in tearDown() so that
  multiple tests can be run from the same test class.

TestScanner2
- changes to make test compatible with the change from inner class
  HClient.RegionLocation to public class HRegionLocation

Leases
- cancelLease just returns if the lease is not found instead of
  throwing an IOException

New:

HConnection - an interface that describes the operations performed by
a connection implementation

HConnectionManager - manages connections for multiple HBase instances
and returns an object that implements HConnection from its static
method getConnection

HBaseAdmin - the HBase administrative methods refactored out of
HClient. Each HBaseAdmin object can control a single HBase
instance. To manipulate multiple instances, create multiple HBaseAdmin
objects. 

HTable - The data manipulation methods refactored out of HClient. Each
HTable object talks to a single table in a single HBase
instance. Create multiple HTable objects to use more than one table.

HRegionLocation - an inner class refactored out of HClient. Each
HRegionLocation has an HRegionInfo object and an HServerAddress
object.

HClient - totally re-implemented in terms of the new classes
above. HClient is now deprecated.

Jim Kellerman 5f850fcee4 HADOOP-1516 HClient fails to readjust when ROOT or META redeployed on new region server
Detailed changes:

MiniHBaseCluster
- rewrite abortRegionServer, stopRegionServer - they now remove the
  server from the map of servers.
- rewrite waitOnRegionServer - now removes thread from map of threads

TestCleanRegionServerExit
- reduce Hadoop ipc client timeout and number of retries
- use rewritten stopRegionServer and waitOnRegionServer from MiniHBaseCluster
- add code to verify that failover worked
- moved testRegionServerAbort to separate test file

TestRegionServerAbort
- new test. Uses much the same code as TestCleanRegionServerExit but
  aborts the region server instead of shutting it down
  cleanly. Includes code to verify that failover worked.

hbase-site.xml (in src/contrib/hbase/src/test)
- reduce master lease timeout and time between lease timeout checks so
  that tests will run quicker.

HClient
- Major restructing of code that determines what region server to
  contact for a specific region. The main method findServersForTable
  is now recursive so that it will find the meta and root regions if
  they have not already been located or will re-find them if they have
  been reassigned and the old server can no longer be contacted.
- re-ordered administrative and general purpose methods so they are no
  longer located in seemingly random order.
- re-ordered code in ClientScanner.loadRegions so that if the location
  of the region changes, it will actually try to connect to the new
  server rather than continually trying to use the connection to the
  old server.

HLog
- use HashMap<Text, SequenceFile.Writer> instead of 
  TreeMap<Text, SequenceFile.Writer> because the TreeMap would return
  a value for a key it did not have (it was the value of another
  key). I have observed this before when the key is Text, but could
  not create a simple test case that reproduced the problem.
- added some new DEBUG level logging
- removed call to rollWriter() from closeAndDelete(). We don't need to
  start a new writer if we are closing the log.

HLogKey
- cleaned up per HADOOP-1466 (I initially modified it to add some
  debug logging which was later removed, but when I was making the
  modifications I took the opportunity to clean up the file)
- changed toString() format

HMaster
- better handling of RemoteException
- modified BaseScanner
 - now knows if it is scanning the root or a meta region
 - scanRegion no longer returns a value
 - if scanning the root region, it counts the number of meta regions
   it finds and sets a new AtomicInteger, numberOfMetaRegions when the
   scan is complete.
 - added abstract methods initialScan and maintenanceScan this allowed
   run method to be implemented in the base class.
- boolean rootScanned is now volatile
- modified RootScanner
 - moved actual scan into private method for readability (scanRoot)
 - implementation of abstract methods just call scanRoot
- add constructor for inner static class MetaRegion
- use a BlockingQueue to queue up work for the MetaScanner
- clean up handling of an unexpected region server exit
- PendingOperation.process now returns a boolean so that HMaster.run
  can determine if the operation completed or needs to be retried later
- PendingOperation processing no longer does a wait inside the process
  method since this might cause a deadlock if the current operation is
  waiting for another operation that has yet to be processed

HMsg
- removed MSG_REGIONSERVER_STOP_IN_ARRAY, MSG_NEW_REGION
- added MSG_REPORT_SPLIT

HRegionServer
- changed reportSplit to contain old region and new regions
- use IP from default interface rather than host name
- abort calls HLog.close() instead of HLog.rollWriter()

Michael Stack 655728f3bf HADOOP-1523 'Hung region servers waiting on write locks'
On shutdown, region servers and masters were just cancelling leases
without letting 'lease expired' code run -- code to clean up
outstanding locks in region server.  Outstanding read locks were
getting in the way of region server getting necessary write locks
needed for the shutdown process.  Also, cleaned up messaging around
shutdown so its clean -- no timeout messages as region servers try
to talk to a master that has already shutdown -- even when region
servers take their time going down.
M src/contrib/hbase/conf/hbase-default.xml
    Make region server timeout 30 seconds instead of 3 minutes.
    Clients retry anyways. Make so its likely region servers report
    in their shutdown message before their lease expires on master.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/Leases.java
    (closeAfterLeasesExpire): Added.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionServer.java
    Added comments.
    (stop): Converted from public to default access (master shuts
    down regionservers).
    (run): Use leases.closeAfterLeasesExpire instead of leases.close.
    Changed log of main thread exit from DEBUG to INFO.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
    (letRegionsServersShutdown): Add better explaination of shutdown
    process to method doc.  Changed timeout waits from
    hbase.regionserver.msginterval to threadWakeFrequency.
    (regionServerReport): If closing, we used to immediately respond
    to region server with a MSG_REGIONSERVER_STOP.  This meant that
    we avoided handling of the region servers MSG_REPORT_EXITING sent
    on shutdown so region servers had no chance to cancel their lease
    in the master.  Reordered.  Moved sending of MSG_REGIONSERVER_STOP
    to after handling of MSG_REPORT_EXITING.  Also, in handling of
    MSG_REGIONSERER_STOP removed cancelling of leases.  Let leases
    expire normally (or get cancelled when the region server comes in
    with MSG_RPORT_EXITING).
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMsg.java
    (MSG_REGIONSERVER_STOP_IN_ARRAY): Added.
