Cassandra-Cli拒絕連接

Question

我正在嘗試連接cassandra。 我安裝了最新的穩定版本apache-cassandra-1.2.4並將其解壓縮到我的桌面上。 當我運行cassandra時，它可以很好地監聽thrift客戶並顯示以下內容：

現在，當我運行時：cassandra-cli -h localhost -p 9160，它拋出了錯誤。 我已經檢查端口是否空閑，而cassandra正在端口上監聽。 ：

Answer 1

我有同樣的錯誤，現在可以了。

主要問題是配置錯誤。

我的配置如下：

我的視覺機器ip是192.168.11.11。我的cassandra已安裝到機器中，因此我配置了thar

listen_address: 192.168.11.11
rpc_address: 0.0.0.0
broadcast_rpc_address: 192.168.11.11

那沒問題。

Answer 2

cassandra-stress的文檔似乎很粗略。 也許在適當的時候將其糾正。 到目前為止，此命令對我有用

./cassandra-stress write -node <IP_OF_NODE1>

一旦可行，我們可以嘗試輸入其他可選參數來調整命令。

Answer 3

選項1：

Run jps command under root user and kill CassandraDaemon if you will see it. After this you will start Cassandra again.

選項2：

Try to connect Cassandra with CQL 
  ./cqlsh 10.234.31.232 9042

最終檢查：

An intermediate firewall is blocking the JVM from making the connection. 
An operating system firewall, or antivirus that is causing the problems as well.

我認為您安裝在Windows中，看起來防火牆阻止了您的連接。
