SELECT * FROM regular_table; 

After a long time, shows the error: 

Error in acquireLocks...

Hive uses ZooKeeper to implement its locking facility, which is then used as a basis of concurrency support, that is, to support concurrent read/write to a same table/partition without causing any corruption to table data/metadata. You can find more details about locking in Hive in following page:
