------------------------------------------
Summary: Ignite hangs during getting of atomic structure after
autoactivation
Key: IGNITE-8987
URL: https://issues.apache.org/jira/browse/IGNITE-8987
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 2.4
Reporter: Andrey Aleksandrov
Fix For: 2.7
Attachments: reproducer.java
I investigate the use cases with autoactivation and creating of the
IgniteAtomicSequence. It hangs on awaitInitialization() method in case if it
called after the last node from BLT was started.
Steps to reproduce:
First iteration:
Do next in one thread:
1)Start server 1
2)Start server 2
3)Activate the cluster
4)Create the IgniteAtomicSequence using next code:
IgniteAtomicSequence igniteAtomicSequence = ignite.atomicSequence(
"TestName",
atomicConfiguration,
10,
true);
Second iteration:
1)Start server 1
2)Start server 2 (Autoactivation will be started)
3)Get the IgniteAtomicSequence using next code:
IgniteAtomicSequence igniteAtomicSequence = ignite.atomicSequence(
"TestName",
10,
true); //could be false because TestName was already created in iteration 1
In this case, we hang in awaitInitialization() method in
DataStructureProcessor.getAtomic() method.
In case if I added some sleep timeout between step 2 and 3 in the second
iteration then everything was ok. Looks like we have some race here.
