Subject [jira] [Commented] (HCATALOG-36) Support Writing Out to Multiple Tables in HCatOutputFormat
Date Thu, 02 Jun 2011 03:40:47 GMT


Ranjit Mathew commented on HCATALOG-36:

Yes, writing to multiple partitions is a sorely-needed feature that we're looking forward
to in HCatalog 0.2.

We process several logs in a MapReduce Job and write out the processed data into various
tables managed by HCatalog. There are multiple tables even for a single log-type, to separate
out the "core" data required in most queries from the "peripheral" data required only in some
queries, not to mention to keep the schema for each table relatively simple.
