[Bug]: NodeNotFound when trying to load collection after milvus update and bulk insert

[zhengbuqian]

Is there an existing issue for this?

• I have searched the existing issues

Environment

- Milvus version: master
- Deployment mode(standalone or cluster): standalone

Current Behavior

hello_milvus.py mentioned below does create collection, insert data, create index and load index. It does not drop index or colelction. bulk pytest refer to cd tests/python_client/testcases && pytest test_bulk_insert.py::TestBulkInsert::test_bulk_insert_all_field_with_parquet.

Before every test, everything in etcd and minio are dropped to ensure fresh start.

Commit order: 5c6de47 (3 days ago) -> c6e2dd05 (19 hours ago) -> a7f6193bfc (10 hours ago) -> now (0520 9 pm)

Test A:

1. built milvus on commit 5c6de47, run hello_milvus.py
2. run bulk pytest. all tests passed

Test B:

1. built milvus on commit 5c6de47, run hello_milvus.py
2. rebuilt milvus on commit a7f6193bfc
3. run bulk pytest. the test fails with NodeNotFound error when trying to load the collection <MilvusException: (code=65535, message=NodeNotFound)> (api_request.py:46)

Test C:

1. built milvus on commit 5c6de47, run hello_milvus.py
2. rebuilt milvus on commit c6e2dd05
3. run bulk pytest all tests passed

Test D:

1. built a7f6193bfc, run hello_milvus.py
2. run bulk pytest. all tests passed

From the above test results, seems commit a7f6193bfc has introduced some kind of compatibility issue, causing collections with segments created by bulk insert fail to load.
