Alexei Scherbakov created IGNITE-4499: -----------------------------------------
Summary: TcpDiscoverySpi is not reliable in some network split scenarios. Key: IGNITE-4499 URL: https://issues.apache.org/jira/browse/IGNITE-4499 Project: Ignite Issue Type: Bug Components: general Affects Versions: 1.6 Reporter: Alexei Scherbakov Fix For: 2.0 Where is a possible caveat in current discovery implementation using ring of nodes. Imagine grid consisting of nodes A B C D Let them form the ring: A-B-C-D-A If network connectivity issues will arise between nodes A-C and B-D discovery spi will never know it and will continue to assume the topology is valid. On other side, TcpCommunicationSpi will try to run transaction on this topology and never will succeed. We must drop nodes from topology on communication spi errors. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
