I am trying to access hive from denodo platform, but I get the following error message
"Unable to establish connection: Could not open client transport with JDBC Uri: jdbc:hive2://hostname:portnumber: java.net.ConnectException: Connection refused: connect ".
It used to work with the same configuration before and has stopped working abruptly. On checking the hive.log file , this is what I found:
> ERROR [pool-3-thread-5]: server.TThreadPoolServer (TThreadPoolServer.java:run(294)) - Thrift error occurred during processing of message.
org.apache.thrift.protocol.TProtocolException: Missing version in readMessageBegin, old client?

at java.lang.Thread.run(Thread.java:748)
I restarted the services, Safemode was OFF for Namenode, the Firewall for our remote server is off and the JDBC drivers are properly configured.
I am unable to debug the log file, any help would be appreciated.
