[jira] [Created] (IGNITE-6448) Select * doesn't return new field
name after concurrent ALTER TABLE
Ilya Suntsov created IGNITE-6448:
------------------------------------
Summary: Select * doesn't return new field name after concurrent ALTER TABLE
Key: IGNITE-6448
URL: https://issues.apache.org/jira/browse/IGNITE-6448
Project: Ignite
Issue Type: Bug
Components: sql
Affects Versions: 2.1
Reporter: Ilya Suntsov
Priority: Blocker
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 [schemaName=PUBLIC, pageSize=1024, maxRows=0, sqlQry=alter table person add field1 varchar, args=[], stmtType=ANY_STATEMENT_TYPE]]

{noformat}
2. When I try to get all data from Person:
{noformat}select * from person;{noformat}
I get the table without new field but if try to get only this field from table it works.
