Description

To open a hiveconnection we have to

HiveConnection connection = null;

try {
connection = new HiveConnection(uri, new Properties());
} finally {
if (connection != null)
try {
connection.close();
} catch (SQLException e) {
LOGGER.error("Error closing connection, ignored.", e);
}
}

HiveConnection opens the opensTransport and tries to create a session in the constructor.

If opensTransport succeed, but session creates fails because of namenode error or any other error, HiveConnection can't be closed.

Since construction fails, the hiveconnection object will be null and the client can't close it.
