Hi All, Please excuse my limited knowledge . We have an application in .Net and the backend database is Cassandra.We have deployed in our application into production which is behing the Firewall. We have opened the 9042 Port from our Webserver to the cassandra cluster. But again we are getting the below error
*INFO [SharedPool-Worker-1] 2015-08-27 11:07:20,679 Message.java:532 - Unexpected exception during request; channel = [id: 0x12af6143, /192.168.16.198:2159 <http://192.168.16.198:2159> => /10.253.2.53:9042 <http://10.253.2.53:9042>]* *java.io.IOException: Error while read(...): Connection timed out* * at io.netty.channel.epoll.Native.readAddress(Native Method) ~[netty-all-4.0.23.Final.jar:4.0.23.Final]* * at io.netty.channel.epoll.EpollSocketChannel$EpollSocketUnsafe.doReadBytes(EpollSocketChannel.java:675) ~[netty-all-4.0.23.Final.jar:4.0.23.Final]* * at io.netty.channel.epoll.EpollSocketChannel$EpollSocketUnsafe.epollInReady(EpollSocketChannel.java:714) ~[netty-all-4.0.23.Final.jar:4.0.23.Final]* * at io.netty.channel.epoll.EpollEventLoop.processReady(EpollEventLoop.java:326) ~[netty-all-4.0.23.Final.jar:4.0.23.Final]* * at io.netty.channel.epoll.EpollEventLoop.run(EpollEventLoop.java:264) ~[netty-all-4.0.23.Final.jar:4.0.23.Final]* * at io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:116) ~[netty-all-4.0.23.Final.jar:4.0.23.Final]* * at io.netty.util.concurrent.DefaultThreadFactory$DefaultRunnableDecorator.run(DefaultThreadFactory.java:137) ~[netty-all-4.0.23.Final.jar:4.0.23.Final]* * at java.lang.Thread.run(Thread.java:745) [na:1.7.0_65]* We have a 5 node cluster and added the static routing to all the node for port 9042 .
