Hive Query Error

I am getting this error when querying on hive:
Your query has the following error(s):

Failed to open new session: java.lang.RuntimeException: java.lang.RuntimeException: java.net.ConnectException: Call From ip-172-31-13-154.ec2.internal/172.31.13.154 to ip-172-31-53-48.ec2.internal:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

Hi @nbatra,

Apologies for the inconvenience.

We were running migrations scripts that time to keep cluster healthy. It should work fine now.

Thanks
