Hi Hasitha, I tried to run metcat and all the servers started successfully but when I try to connect to cassendra using cassendra-gui I get following error. FYI I had to change the JMX port from 8080 to 7199. I want to ask whehter this is correct or not ? I left the Thrift port as it is.
Is there any other way to look in to cassendra data ? What will be your plan to write a client to read the cassendra data and retrive meaningful information from the database ?
