-------------------------------------
Summary: Concurrent Error when multiple JDBC client send queries
Key: IOTDB-366
URL: https://issues.apache.org/jira/browse/IOTDB-366
Project: Apache IoTDB
Issue Type: Bug
Affects Versions: 0.10.0-SNAPSHOT
Reporter: Xiangdong Huang
HI,
After the SQL parser is upgraded to Antlr4, seems a concurrent error is
introduce.
The error can be reproduced by:
In org.apache.iotdb.db.integration.IoTDBQueryDemoIT class, add a new test
function:
{code:java}
// code placeholder
@Test
public void testConcurrent() {
new Thread(new Runnable() {
@Override
public void run() {
try {
selectTest();
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
new Thread(new Runnable() {
@Override
public void run() {
try {
selectTest();
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
}
{code}
Notice, because it is a concurrent error, the issue is not reproduced every
time.
And, the exceptions in the above test function can not be caught by Junit, so
it is not a formal UT code.
