I have a main thread that opens a JDBC connection to HiveServer2, this connection object is shared by multiple threads. The thread has a prepared statement and executes a select query(not CRUD) and does some processing with the resultset.
I am trying this with Hive as I have some legacy code from the product I work on which I dont want to change and I know that this works with Oracle.
Below is the stack trace of the exception.

Trying to understand if this is a limitation.
