> Run a hiveserver2 instance "hive --service hiveserver2".
> Then from another console, connect to hiveserver2 "beeline -u
> "jdbc:hive2://localhost:10000"
> When you run a MR job like "select t1.key from src t1 join src t2 on
> t1.key=t2.key", some of the console logs like MR job info are not printed to
> the console while it just print to the hiveserver2 console.
> When hive.async.log.enabled is set to false and restarts the HiveServer2,
> then the output will be printed to the beeline console.
> OperationLog implementation uses the ThreadLocal variable to store associated
> the log file. When the hive.async.log.enabled is set to true, the logs will
> be processed by a ThreadPool and the actual threads from the pool which
> prints the message won't be able to access the log file stored in the
> original thread.
