The real reason is probably in the log of the hiveserver. It should be in the console you started the hiveserver in. I sometimes start it like this: nohup ./hive --service hiveserver >hive.log & Which would show you some errors in the hive.log file. We used to have some problems with PermGen issues because of a classloading/unloading issue in one of our udfs which would show itself with an error like this. It is however a pretty generic error which is telling you the "hiveserver" is probably having a problem and you need to take a look at the logs.
