Alexander Belyak updated IGNITE-21776:
--------------------------------------
Description:
In two parallel clients:
1) Run DDL (using two clients):
```
create table if not exists parallelCreateTable0
(id INTEGER not null,
val VARCHAR not null,
primary key (id))
```
2) Get parallelCreateTable0 using ignite.tables() API or select from jdbc
Expected result:
# One client creates the table, second one - wait table created
# Both client can use the table
Actual result:
# One client creates the table, second one return control immediatly
# Second client fails to use the table, first one works as expected after the
table creating finished.
