一个AWS实例安装并运行了Cassandra（2.1.16）。另一个AWS实例没有安装Cassandra，但使用的是apache-cassandra-2.1.16二进制文件中的sstableloader程序。 sstableloader服务器上使用的cassandra.yaml具有以下设置：
cluster_name：＆＃39;测试群集＆＃39; listen_address： storage_port：7000 rpc_address：0.0.0.0 rpc_port：9160
两台服务器都使用相同的AWS安全组，该组具有以下端口：
7000,9160
当我像这样执行ssltableloader时：
./sstableloader -d <CassandraNode> -f ../../cassandra/cassandra.yaml -v ../../cassandra/<Keyspace>/<CFName>/
我收到此错误：
Established connection to initial hosts

我已成功使用本地PC上的sstableloader将数据加载到AWS上的Cassandra节点。我失败的地方是当我尝试从一个ASW实例到另一个ASW实例的sstableloader时。
对于完整的披露，我也尝试过在2个实例之间打开的所有端口，这会导致同样的失败。
在尝试执行sstableloading的实例上是否缺少配置步骤？
答案 0 :(得分：0)
Cassandra节点使用其公共IP作为其broadcast_address。当我在我的盒子里使用sstableloader时，这个工作正常。尝试从另一个AWS实例使用sstableloader时失败，因为该服务器无法通过其公共IP找到Cassandra节点。我能够通过使用Cassandra节点的私有IP作为broadcast_address来使其工作。
