Igor resolved IGNITE-22139.
---------------------------
Resolution: Cannot Reproduce
> JDBC request to degraded cluster freezes forever
> ------------------------------------------------
>
> Key: IGNITE-22139
> URL: https://issues.apache.org/jira/browse/IGNITE-22139
> Project: Ignite
> Issue Type: Bug
> Components: general, jdbc, networking, persistence
> Affects Versions: 3.0.0-beta1
> Environment: The 2 or 3 nodes cluster running locally.
> Reporter: Igor
> Priority: Major
> Labels: ignite-3
>
> *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:*
> The select query at step 9 freezes forever.
