             Summary: Blocked drop table operations cause strange issues
                 Key: IGNITE-10897
                 URL: https://issues.apache.org/jira/browse/IGNITE-10897
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.7, 2.6
            Reporter: JiajunYang

Reproduce steps to get a blocked drop table operation:

1.Create a table and put some data to a node with persistence enabled. 
2.Do a select query targeting on the table which runs long time. 
3.Drop the table before the select query end. 
Then u will see drop table operation blocks until the select query end.

A strange issue cause by blocked drop table operations:

1.Do another drop table operation when there is a blocked drop table operation.This operation
will also block.

2.Try to recreate the table with same name.When you can see "table 
already exists" exception. 

3.Try to drop the table again,then you can see 
"Table doesn't exist" exception.
