Igor created IGNITE-22513:
-----------------------------
Summary: Failed to get the primary replica if non CMG node is down
Key: IGNITE-22513
URL: https://issues.apache.org/jira/browse/IGNITE-22513
Project: Ignite
Issue Type: Bug
Components: general, jdbc, networking, persistence, rest
Affects Versions: 3.0.0-beta1, 3.0.0-beta2
Environment: The 2 or 3 nodes cluster running locally.
Reporter: Igor
Assignee: Aleksandr Polovtsev
*Steps to reproduce:*
# Create zone with replication equals to amount of nodes (2 or 3 corresponding)
# Create 10 tables inside the zone.
# Insert 100 rows in every table.
# Await all tables*partitions*nodes local state is "HEALTHY"
# Await all tables*partitions*nodes global state is "AVAILABLE"
# Kill first node with kill -9.
# Assert all tables*partitions*nodes local state is "HEALTHY"
# Await all tables*partitions*nodes global state is "READ_ONLY" for 2 nodes
cluster or "DEGRADED" for 3 nodes cluster,
# Execute select query using JDBC connecting to the second node (which is
alive).
*Expected:*
Data is returned.
*Actual:*
On the step 7 it returns error by REST API:
