If > HiveServer2 is configured to run in parallel and the query involves many > tasks, then the connections are created but unused. > {noformat} > @Override > public void run() { > runner = Thread.currentThread(); > try { > OperationLog.setCurrentOperationLog(operationLog); > SessionState.start(ss); > runSequential(); > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
