> ---------------------------------------------------------
>
> Key: IGNITE-21663
> URL: https://issues.apache.org/jira/browse/IGNITE-21663
> Project: Ignite
> Issue Type: Bug
> Components: persistence, sql
> Affects Versions: 3.0.0-beta1
> Reporter: Igor
> Priority: Major
> Labels: ignite-3
> Fix For: 3.1
>
>
> *Steps to reproduce:*
> # Start cluster with 2 nodes running locally.
> # Make connection like this:
> {code:java}
> try (IgniteClient igniteClient = IgniteClient.builder().retryPolicy(new
> RetryLimitPolicy()).addresses(thinClientEndpoints.toArray(new
> String[]{"localhost:10800","localhost:10801"})).build()) {
> try (Session session = igniteClient.sql().createSession()) {
> //code here
> }
> } {code}
> 3. Create table with replication 2
> 4. Execute insert 1 row and select from the table.
> 5. Kill first node (in list of connection)
> 6. Execute select from the table.
> *Expected:*
> Cluster works with one node.
> *Actual:*
> The exception on select after first node is killed, the select is not
> executed.
