Changed InternalScanner API:
from
{code}
boolean next(HStoreKey, SortedMap<byte[], byte>)
{code}
to
{code}
boolean next(HStoreKey, SortedMap<byte[], Cell>)
{code}
Files changed as a result of API change:
HMerge.java, ColumnValueFilter, PageRowFilter, RegExpRowFilter, RowFilterInterface, RowFilterSet, StopRowFilter, WhileMatchRowFilter, HAbstractScanner, HRegion$HScanner, HRegionServer, HStoreScanner, InternalScanner, Memcache, StoreFileScanner, MetaUtils, HBaseTestCase, TestScannerAPI, TimestampTestBase, TestRegExpRowFilter, TestRowFilterAfterWrite, TestRowFilterOnMultipleFamilies, TestRowFilterSet, TestGet2, TestHMemcache, TestHRegion, TestScanner, TestSplit
Update comments in Flusher
HRegion.internalFlushCache, HStore.flushCache, HStore.internalFlushCache now returns true only if a flush was completed and a compaction is needed.
HRegion.internalFlushCache now includes region name in DroppedSnapshotException
When creating a reader during compaction, don't bother with bloom filter since we won't use it.
StoreFileScanner locks the store for read while it is in the constructor. It also does not load the bloom filter when it opens readers on the store files.
TestScannerTimes - new regression test for HBASE-737

HBASE-681 NPE in Memcache
HAbstractScanner
- remove HAbstactScanner.iterator() - iterator is not a method on InternalScanner
HRegion
- make getScanner more efficient by iterating only once to find the stores we need to scan
- only pass columns relevant to a store to a HStoreScanner
- remove HScanner.iterator() - iterator is not a method on InternalScanner
Memcache, MemcacheScanner
- Fix NPE in Memcache
- never return HConstants.LATEST_TIMESTAMP as the timestamp value for a row. Instead use the largest timestamp from the cells being returned. This allows a scanner to determine a timestamp that can be used to fetch the same data again should new versions be inserted later.
StoreFileScanner
- getNextViableRow would find a row that matched the row key, but did not consider the requested timestamp. Now if the row it finds has a timestamp greater than the one desired it advances to determine if a row with a timestamp less than or equal to the requested one exists since timestamps are sorted descending.
- removed an unnecessary else
testScanMultipleVersions
- Test program that fails on current trunk but passes when this patch is applied.

-Change HServerLoad's getLoad method to ignore the number of requests, thus causing RegionManager to assign based merely on number of regions per server
git-svn-id: https://svn.apache.org/repos/asf/hadoop/hbase/trunk@669533 13f79535-47bb-0310-9956-ffa450edef68
Add in special handling of .META. table that we used have in HQL
(so it prints out the HRegionInfo pretty). Also allow making a scanner
without specifying columns.
M src/java/org/apache/hadoop/hbase/HTableDescriptor.java
Allow getMetadata work if HTable is set against meta tables.
Was failing on isLegalTableName if name was one of the catalog table names.
Needed by shell.
M src/java/org/apache/hadoop/hbase/client/HTable.java
Comment.
M bin/hbase
Remove commented out line.
M bin/HBase.rb
Allow passing just a table name to scanner; let it figure out all families
Added in the special handling of .META. table cells that we used have in HQL
so we can see start/end row, etc. Added in extra testing.
M bin/Formatter.rb
Allow setting width of emitted table in console formatter
M bin/hirb.rb
Allow setting width of emitted table in console formatter
Improved scanner help.:

-Added new test to TestGet2 to highlight multi-storefile getClosestBefore issue
-Removed erroneous return that caused 2nd and subsequent mapfiles to be skipped
-Split HStore#rowKeyAtOrBeforeFromMapfile into two sub-methods for readability

HBASE-650 Add String versions of get, scanner, put in HTable
HBASE-656 Do not retry exceptions such as unknown scanner or illegal argument
A src/java/org/apache/hadoop/hbase/ColumnNameParseException.java
A src/java/org/apache/hadoop/hbase/LeaseException.java
Added. Thrown instead of IllegalArgumentExceptions
M src/java/org/apache/hadoop/hbase/Leases.java
Use new LeaseException in place of IllegalArgument
M src/java/org/apache/hadoop/hbase/HStoreKey.java
Use new ColumnNameParse in place of IllegalArgument
M src/java/org/apache/hadoop/hbase/master/ServerManager.java
Log at debug if LeaseException (Not important if it happens).
A src/java/org/apache/hadoop/hbase/DoNotRetryIOException.java
An IOE that shouldn't be retried.
M src/java/org/apache/hadoop/hbase/InvalidColumnNameException.java
M src/java/org/apache/hadoop/hbase/UnknownScannerException.java
Inherit from DoNotRetryIOException else we keep trying.
M src/java/org/apache/hadoop/hbase/util/Bytes.java
(toByteArrays): Added one to handle [] String.
M src/java/org/apache/hadoop/hbase/client/HTable.java
Make String overrides of all methods. Made data members
private (turns out a bunch arent' even used). Stopped it
inheriting from HConstants so we don't have big dump of
all HConstants as first thing in javadoc.
M src/java/org/apache/hadoop/hbase/client/HConnectionManager.java
If instance of DoNotRetryIOException, let the exception out.
M src/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
Make String overrides of all methods. Stopped it
inheriting from HConstants so we don't have big dump of
all HConstants as first thing in javadoc.

over on the remote side.
M src/test/org/apache/hadoop/hbase/TestSerialization.java
Add test that HMsg with region and message serializes.
M src/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
HMsg types have been enumified. Also use some of the new
static messages. On split and close because of error,
add message to the HMsg we pass back to the master.
M src/java/org/apache/hadoop/hbase/HServerInfo.java
(compareTo): Added.
M src/java/org/apache/hadoop/hbase/HRegionInfo.java
Allow null in compareTo.
M src/java/org/apache/hadoop/hbase/master/ServerManager.java
Use the new HMsg.isType figuring message type.
Redo message logging. Use convenience HMsg statics.
M src/java/org/apache/hadoop/hbase/master/RegionManager.java
Pass back overloaded message if region shutdown because of balancing.
M src/java/org/apache/hadoop/hbase/HServerAddress.java
Make it so that two addresses equate even if one has hostname
and the other IP.
M src/java/org/apache/hadoop/hbase/ipc/HMasterRegionInterface.java
Up the protocol version for regionserver reporting master messages.
M src/java/org/apache/hadoop/hbase/HMsg.java
Enumify the messge types.
Define a few static HMsgs for convenience.
Allow optional message. Improved toString.
(isType, equals, hashCode): Added.

M HMaster
- Moved HMaster.quiescedMetaServers to ServerManager.quiescedServers and changed name since only servers serving user regions get quiesced.
- Removed HMaster.tableInCreation - not used
M ServerManager
- Don't check if quiescedServers.get() >= serversToServerInfo.size() unless master.shutdownRequested is true.
M HRegionServer
- Change order of checks in main loop of HRegionServer.run, so that booleans are checked before we check the number of messages to process
- Don't break out of main loop if restart or stop requested - stop is checked at top of loop and we need to continue rather than break out of main loop if restart was requested
