Hello.Sorry for so late to reply.I have got a reproducer.
Here is the test code.Please run it in a ignite without persistence enabled.
public class ConcurrentCreateTable {
private static Connection conn;
private static Connection conn1;
public static void main(String[] args) throws Exception {
initialize();
new Thread(new Runnable() {
@Override
public void run() {
while (true) {
try (Statement stmt = conn.createStatement()) {
stmt.execute(
"CREATE TABLE IF NOT EXISTS city1(ID
INTEGER,NAME VARCHAR,NAME1 VARCHAR ,PRIMARY KEY(ID)) WITH
\"template=replicated\";"
+ "CREATE INDEX IF NOT EXISTS city1_name ON
city1(NAME);CREATE INDEX IF NOT EXISTS city1_name1 on city1(NAME1);");
stmt.execute("DROP TABLE IF EXISTS city1");
System.out.println("XXX");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}).start();
new Thread(new Runnable() {
@Override
public void run() {
while (true) {
try (Statement stmt = conn1.createStatement()) {
stmt.execute(
"CREATE TABLE IF NOT EXISTS city2(ID
INTEGER,NAME VARCHAR, NAME1 VARCHAR ,PRIMARY KEY(ID)) WITH
\"template=replicated\";"
+ "CREATE INDEX IF NOT EXISTS city2_name ON
city2(NAME);CREATE INDEX IF NOT EXISTS city2_name1 on city2(NAME1);");
stmt.execute("DROP TABLE IF EXISTS city2");
System.out.println("XXX");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}).start();
while (true) {
}
}
private static void initialize() throws Exception {
Class.forName(Config.IGNITE_DRIVER);
final Properties props = new Properties();
conn = DriverManager.getConnection(Config.IGNITE_URL, props);
conn1 = DriverManager.getConnection(Config.IGNITE_URL, props);
}
}
Here is the exception：
java.sql.SQLException: Schema change operation failed: Thread got
interrupted while trying to acquire table lock.
