問題與WSO2 BAM：無法連接到服務器org.apache.hadoop.hive.cassandra.CassandraException：無法連接到服務器

於CentOS操作系統我部署默認的配置一個BAM 2.0.1服務器。之後，我配置AS和ESB工具箱，配置我的AS和ESB服務器以使用此BAM。問題與WSO2 BAM：無法連接到服務器org.apache.hadoop.hive.cassandra.CassandraException：無法連接到服務器
當我重新啓動我開始看到控制檯：

ü沒有更改端口在BAM彌補這一錯誤的BAM服務器？如果是這樣的Hive腳本將需要修改cassandra端口參數。

因爲我看到這是一個隨機錯誤。過了一會兒，我再也看不到它了： - 順便說一下，我在配置文件中沒有改變任何東西。 –
