Ich arbeite mit Cloudera Impala Server Version 5.4.7 zuerst um sicherzustellen, dass der Port offen ist, habe ich es mit Telnet validieren.Verbindung zu Cloudera Impala/Hive außerhalb des Clusters
Class.forName("org.apache.hive.jdbc.HiveDriver");
DriverManager.setLoginTimeout(30);
try (java.sql.Connection connection = DriverManager.getConnection("jdbc:hive2://12.23.56.789:123456/someName;auth=noSasl"))
{ System.out.println("connected"); }
Aber ich nie gelingen
alles, was ich dieser Fehler ist von Timeout erhalten zu verbinden:
, was das Problem sein könnte? ich bin mit der exakt gleichen hive Version als cloudera Version
