Hi, As a starting point you can take a look at org.apache.ignite.spi.discovery.tcp.ServerImpl#forceNextNodeFailure which forces DiscoverySpi to drop next node from the topology (not sure if this is what you need). Another idea is to create a test discovery SPI which will terminate all it's threads when a test flag is set. Such nodes also should be segmented from the topology.
Yakov, do you have other ideas? 2016-08-31 0:06 GMT+03:00 Anand Kumar Sankaran <anand.sanka...@workday.com>: > Hi > > I am implementing a segmentation resolver to handle split brain > scenarios.
