[Cassandra Wiki] Update of "HadoopSupport" by BenFrank

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.

The "HadoopSupport" page has been changed by BenFrank:
http://wiki.apache.org/cassandra/HadoopSupport?action=diff&rev1=54&rev2=55

  
  Also hadoop integration uses range scans underneath which do not do read repair.  However reading at !ConsistencyLevel.QUORUM will reconcile differences among nodes read.  See ReadRepair section as well as the !ConsistencyLevel section of the [[http://wiki.apache.org/cassandra/API|API]] page for more details.
  
+ If you're having trouble with a never ending supply of data when using `ColumnFamilyInputFormat`, make sure you're not altering the `ByteBuffer` key input to the mapper; either by duplicating it first or using one of the absolute accessors.
