[jira] Updated: (PIG-1355) [Zebra] Zebra Multiple Outputs should
enable application to skip records
[ https://issues.apache.org/jira/browse/PIG-1355?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Olga Natkovich updated PIG-1355:
--------------------------------
Fix Version/s: (was: 0.8.0)
Description:
Applications may not always want to write a record to a table. Zebra should allow application to do the same.
Zebra Mutipile Outputs interface allow users to stream data to different tables by inspecting the data Tuple.
https://issues.apache.org/jira/browse/PIG-1111
So,
If ZebraOutputPartition returns -1, Zebra Multiple Outputs will skip that record and thus will not write to any table
However, Zebra BasicTableOutputFormat ( different from Zebra Multiple Outputs ) will write every record to a table
