Subject [Cassandra Wiki] Trivial Update of "HadoopSupport" by jeremyhanna
Date Mon, 25 Jul 2011 19:46:33 GMT
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 jeremyhanna:
http://wiki.apache.org/cassandra/HadoopSupport?action=diff&rev1=36&rev2=37

  If you are seeing inconsistent data coming back, consider the consistency level that you
are reading and writing at.  The two relevant properties are:
   * '''cassandra.consistencylevel.read''' - defaults to !ConsistencyLevel.ONE.
   * '''cassandra.consistencylevel.write''' - defaults to !ConsistencyLevel.ONE.
- Also since 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.
