我試圖從Datastax Java驅動程序連接到啓用kerberos的cassandra安全集羣。卡桑德拉Java驅動程序與Kerberos安全
樣品連接代碼:
cluster = Cluster.builder().addContactPoint(node).withCredentials("username","password").build();
Metadata metadata = cluster.getMetadata();
System.out.printf("Connected to cluster: %s\n",
metadata.getClusterName());
for (Host host : metadata.getAllHosts()) {
System.out.printf("Datatacenter: %s; Host: %s; Rack: %s\n",
host.getDatacenter(), host.getAddress(), host.getRack());
}
session = cluster.connect();
我得到下面的錯誤:

我正在使用DSE版本3.1.3。 Java驅動程序1.0.3-dse。
我沒有發現任何錯誤,指出「獲取服務器標識的主題時出錯」。這些是我嘗試連接時的服務器日誌 – Ram
