---------------------------------
Summary: Constraint import may fail during incremental replication
Key: HIVE-17497
URL: https://issues.apache.org/jira/browse/HIVE-17497
Project: Hive
Issue Type: Bug
Components: repl
Reporter: Daniel Dai
Assignee: Daniel Dai
During bootstrap repl dump, we may double export constraint in both bootstrap
dump and increment dump. Consider the following sequence:
1. Get repl_id, dump table
2. During dump, constraint is added
3. This constraint will be in both bootstrap dump and incremental dump
4. incremental repl_id will be newer, so the constraint will be loaded during
incremental replication
5. since constraint is already in bootstrap replication, we will have an
exception
