> --------------------------------------------------

> Key: IGNITE-2671
> URL: https://issues.apache.org/jira/browse/IGNITE-2671
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.5.0.final
> Reporter: Vladimir Ozerov
> Priority: Critical
> Labels: community
> Fix For: 1.7
>
>
> The problem is originally reported by Mario:
> http://apache-ignite-users.70518.x6.nabble.com/Semaphore-blocking-on-tryAcquire-while-holding-a-cache-lock-td3031.html
> *Description*
> When a lock is held on a cache key, another node cannot join topology. It
> hangs somewhere on partition exchange future.
> *Steps to reproduce*
> Run the following code and observe that ">>> STARTED 2" is never printed
> because we cannot leave Ignition.start() method.
> {code}
> public static void main(String[] args) {
> // Start the first node.
> Ignite ignite = Ignition.start(new
> IgniteConfiguration().setGridName("1"));
> System.out.println(">>> STARTED 1");
> // Create cache and obtain a lock on it.
> CacheConfiguration<String, String> ccfg =
> new CacheConfiguration<String,
> String>().setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
> ignite.getOrCreateCache(ccfg).lock("key").lock();
> System.out.println(">>> LOCKED");
> Ignition.start(new IgniteConfiguration().setGridName("2"));
> System.out.println(">>> STARTED 2");
> }
> {code}
