the cluster method from ESIntegTestCase.java returns a TestCluster. It seems that the behavior of the output of httpAddresses of cluster() is different between 7.0 and 6.0. In the 7.0 version cluster().httpAddresses() returns 0.0.0.0:0 In the 6.0 version cluster().httpAddresses() returns 127.0.0.1:49753 and 127.0.0.1:49754 Is it expected? ---

I have same problem. It is because in v7 there is actually MockHttpTransport used which is reporting 0.0.0.0:0. In v6 Netty4HttpServerTransport is used. I don't know why. Which HttpServerTransport will be used is decided in InternalTestCluster.getInstances(HttpServerTransport.class) and that is somehow related to node. I think MockHttpTransport should not be choosed in InternalTestCluster in ESIntegTestCase. Someone from elasticsearch should shed some light on this. ---

Hi @mbrunat After some research, I found the root issue was ES deprecated embedded cluster in ES7.0, which made all unit tests failing. Definitely would be helpful if someone from ES could confirm this. ---

Strange, either InternalTestCluster nor TestCluster is not annotated as deprecated, even in 7.4. Where is that information coming from? ---

InternalTestCluster.buildNode prepares MockNode which newHttpTransport() method creates MockHttpTransport if plugin MockHttpTransport.TestPlugin is enabled. So solution can be to disable this plugin. I'll try ... ---

Oh, ESIntegTestCase.addMockHttpTransport() override ---

@mbrunat I read about it from some ES Github discussion. Couldn't find the post. ---
