Hi, Igniters. The discovery custom message interface has two methods the use of which is not clear to developers:
1. The stopProcess() method. Currently, it works only if the zookeeper discovery configured. It doesn't work in TcpDiscoverySpi. I did not find any usages of this method except tests. I suggest to remove it from the discovery custom message interface. 2. The isMutable() method. It works in TcpDiscoverySpi but not in the zookeeper SPI. Using this method is opaque to the developer when he wants to add new features to the project. In general, it cannot be used because may not be supported depending on the configuration. Perhaps some functionality that uses it is not working correctly with zookeeper configured. It seems we should avoid it in the custom message interface too. WDYT? -- Best wishes, Amelchev Nikita
