This commit modifies ESSingleNodeTestCase and ESIntegTestCase and several concrete test classes to use node names when bootstrapping the cluster. Today ClusterBootstrapService.INITIAL_MASTER_NODE_COUNT_SETTING setting is used to bootstrap clusters in tests. Instead, we want to use ClusterBootrstapService.INITIAL_MASTER_NODES_SETTING and get rid of the former setting eventually. There were two main problems when refactoring InternalTestCluster: 1. Nodes are created one-by-one in buildNode method. And node.name is created in this method as well. It's not suitable for bootstrapping, because we need to have the names of all master eligible nodes in advance, before creating the node with bootstrapping configuration set. We address this issue by separating buildNode into two methods: getNodeSettings and buildNode. We first iterate over all nodes to get nodes settings, then change the setting for the bootstrapping node and then proceed with building the node. 2. If autoManageMinMasterNodes = false, there is no way for the test to set the list of bootstrapping nodes because node names are not known in advance. This problem is solved by adding updateNodesSettings method to NodeConfigurationSource and ESIntegTestCase (which could be overridden by concrete integration test class). Once we have the list of settings for all nodes, the integration test class is allowed to update it. In our case, we update the ClusterBootrstapService.INITIAL_MASTER_NODES_SETTING setting. |
