> Zebra enables application to stream data into different zebra table instances.
> New Interface added:
> setMultipleOutputs( JobConf jobconf, String commaSeparatedLocation, Class<? extends
ZebraOutputPartitioner> theClass.
> Zebra maintains a list of tables instances based on commaseparatedlocations ( in that
order )
> ZebraOutputPartitioner interface has getOutputPartition method which is implemented by
the application. It will return an index into the list. Zebra will write to that instance
> We also introduce a new mapred property for setting multiple outputs.
> mapred.lib.table.multi.output.dirs
