> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 2.1
> Reporter: Ilya Suntsov
> Assignee: Taras Ledkov
> Priority: Critical
> Fix For: 2.3

> Steps for reproduce:
> 1. Start 3 nodes
> 2. Execute
> {noformat}CREATE TABLE person (id LONG, name VARCHAR, city_id LONG, PRIMARY
> KEY (id, city_id)) {noformat}
> to create table Person
> 3. Connect to grid via sqlline (https://github.com/julianhyde/sqlline)
> {noformat}./sqlline -d org.apache.ignite.IgniteJdbcThinDriver --color=true
> --verbose=true --showWarnings=true --showNestedErrs=true -u
> jdbc:ignite:thin://127.0.0.1/{noformat}
> 4. Create one more connection {noformat}!connect
> jdbc:ignite:thin://127.0.0.1/ {noformat}
> 5. Execute ALTER TABLE for both connections {noformat} !all alter table
> person add field1 varchar;{noformat}
> Result:
> 1. Got exception on coordinator:
> {noformat}[10:59:15,805][SEVERE][client-connector-#55%null%][JdbcRequestHandler]
> Failed to execute SQL query [reqId=0, req=JdbcQueryExecuteRequest
