Problem related with MySQL for Hive settings:

mysql> show global variables like ‘%time%’ ;

update it make it something like 28800 (default)

mysql> SET GLOBAL wait_timeout = 28800;

update my.cnf to update it permanent by adding:

wait_timeout = 28800

Or you can set interactiveClient=true in the JDBC connection string. Which uses an alternative timeout period.
