Eugene Koifman commented on HIVE-13961:
---------------------------------------

I think testNonAcidToAcidConversion3() would be better if step 4 did an update 
or delete instead of insert.
That way it will also check that ROW__IDs assigned to "pre-acid" rows by 
compaction are consistent with other operations.
Similar to testNonAcidToAcidConversion2()

> ACID: Major compaction fails to include the original bucket files if there's 
> no delta directory

> The issue can be reproduced by steps below:
> 1. Insert a row to Non-ACID table
> 2. Convert Non-ACID to ACID table (i.e. set transactional=true table property)
> 3. Perform Major compaction
