-------------------------------------
Summary: non Acid to acid conversion doesn't handle _copy_N files
Key: HIVE-16177
URL: https://issues.apache.org/jira/browse/HIVE-16177
Project: Hive
Issue Type: Bug
Components: Transactions
Reporter: Eugene Koifman
Priority: Critical
insert into T(a,b) values(1,2)
insert into T(a,b) values(1,3)
//we should now have bucket files 000001_0 and 000001_0_copy_1
but OrcRawRecordMerger.OriginalReaderPair.next() doesn't know that there can be
copy_N files and numbers rows in each bucket from 0 thus generating duplicate
IDs
[~owen.omalley], do you have any thoughts on a good way to handle this?
attached patch has a few changes to make Acid even recognize copy_N but this is
just a pre-requisite. The new UT demonstrates the issue.
