[jira] Updated: (PIG-1111) [Zebra] multiple outputs support
[ https://issues.apache.org/jira/browse/PIG-1111?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jing Huang updated PIG-1111:
----------------------------
Description:
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
