Alexander Lapin resolved IGNITE-22514.
--------------------------------------
Resolution: Not A Problem
> Failed to get the primary replica if non CMG node is down
> ---------------------------------------------------------
>
> Key: IGNITE-22514
> URL: https://issues.apache.org/jira/browse/IGNITE-22514
> Project: Ignite
> Issue Type: Bug
> Components: general, jdbc, networking, persistence
> Affects Versions: 3.0.0-beta2
> Environment: The 2 nodes cluster (1 CMG node).
> Reporter: Igor
> Priority: Major
> Labels: ignite-3
> Attachments: CMG node.zip, non CMG killed node.zip
>
>
> *Steps to reproduce:*
> # Start cluster of 2 nodes with one CMG node.
> # Create zone with replication equals to amount of nodes (2).
> # 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 *non CMG* node with kill -9.
> # Assert physical topology contains only 1 alive node.
> # Assert logical topology contains only 1 alive node.
> # Await all tables*partitions*nodes local state is "HEALTHY"
> # Await all tables*partitions*nodes global state is "READ_ONLY".
> # Execute select query using JDBC connecting to the *alive CMG* node.
> *Expected:*
> Data is returned.
> *Actual:*
> The exception on step 12 occurs:
> {code:java}
> Failed to get the primary replica [tablePartitionId=10_part_1]
> java.sql.SQLException: Failed to get the primary replica
> [tablePartitionId=10_part_1]
