Subject [jira] [Commented] (HCATALOG-36) Support Writing Out to Multiple Tables in HCatOutputFormat
Date Wed, 01 Jun 2011 15:32:47 GMT


Alan Gates commented on HCATALOG-36:

Writing to multiple partitions is slated for 0.2, see

I'd like to understand the use case for writing to multiple tables.  You want to be able to
split the output stream to different tables as it's being written?  How would the split be
determined?  Can you give me an example of a job that would want to do this?  Also, using
Pig's split operator and HCatStorer this should already work in Pig.  Would an extending MultipleOutputFormat
do what you want?
