我正在尝试设置Datastax OpsCenter。
当我尝试运行datastax-agent时，出现以下错误：
Can't connect to Cassandra (All host(s) tried for query failed (tried:
/X.X.X.X1:9042 (com.datastax.driver.core.exceptions.TransportException:
[/X.X.X.X1:9042] Cannot connect), /X.X.X.X2:9042

/X.X.X.X6:9042 [only showing errors of first 3 hosts, use getErrors()
for more details])), retrying soon.
如果需要其他详细信息，请告诉我。
