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

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

This commit finishes up the DDL
M src/test/org/apache/hadoop/hbase/TestBloomFilters.java
Changed name of default constants.

Changed name of default constants.
(getNameAsString): Added.
M src/java/org/apache/hadoop/hbase/master/ModifyColumn.java
toString column family byte array name.
M bin/HBase.rb
(alter, hcd): Added.
M bin/hirb.rb
More help doc.
(alter, admin): Added.

M bin/HBase.rb
Remove Module-level constants. Move them instead back into
HColumnDescriptor, etc. and read them from there.
(describe): Added.
M bin/hirb.rb
Fixed up comments. Added TODOs.
Add here the constants from HColumnDescriptor and HTableDescriptor
Use HERE doc. for main help.
