Mo created IGNITE-9767: -------------------------- Summary: Network partition leads to failures in Ignite's semaphore Key: IGNITE-9767 URL: https://issues.apache.org/jira/browse/IGNITE-9767 Project: Ignite Issue Type: Bug Affects Versions: 2.4 Reporter: Mo
Creating a network partition in a replicated Ignite cluster leads to creating two independent clusters, each of which would operate independently from the other, even after the network partition is healed. Setup: 3 servers (s1,s2,s3) two clients (c1,c2). A partition created \{(s1,s2,c1),(s3,c2)}. --> At this point two independent clusters form; one containing s1 and s2, while the other containing s3. The two never rejoin even after the partition is healed. This leads to a faulty semaphore on both sides of the partition. For example, if a semaphore with one permit is created in the cluster, after creating a network partition and healing it, both *c1* and *c2* can acquire that one permit. System config: Release acquired permits if node, that owned them, left topology ==> Set to true -- This message was sent by Atlassian JIRA (v7.6.3#76005)
