Eugene Koifman updated HIVE-17089:
----------------------------------
Description:
acid 2.0 is introduced in HIVE-14035. It replaces Update events with a
combination of Delete + Insert events. This now makes U=D+I the default (and
only) supported acid table type in Hive 3.0.
The expectation for upgrade is that Major compaction has to be run on all acid
tables in the existing Hive cluster and that no new writes to these table take
place since the start of compaction. Then upgrade to Hive 3.0 can take place.
