Subject [jira] Commented: (PIG-17) Make Pig work with Hadoop 0.15
Date Mon, 19 Nov 2007 19:23:45 GMT

Olga Natkovich commented on PIG-17:
-----------------------------------

The attachement contains all the changes needed to transition to hadoop 0.15. Note that the
changes are not backward compatible - once applied, the trunk will no longer work with earlier
versions of hadoop.

All unit tests and about 75 end-to-end tests ran successfully.
