I have looked around for a solution to find whether hive is running or not? I found it to be running. I used beeline to access hive. applied some commands. the commands were responded properly. here is a screenshot

At a place I read that, this error may occur due to Zookeeper service failure. I tried that too and the results are as follows.

Any help in this regard!
