Many training institutions and training tutorials have taken the "OSI Reference Model" as the beginning of the curriculum, which is a very important foundation for our learning network. The following is the OSI structure diagramOSI: Layer Seventh Application layer (application)Sixth Layer Presentation layer (Presentation)Level fifth sessionFourth layer Transport Layer (TRANSPORT)Third Layer Network layer (nerwork): IP, ARP, ICMP and other protocols, routing equipment, inter-network data transmis

Hive in layman 's1. What is Hive1) What is hive?Here is an introduction to the Hive wiki:Hive is a data warehouse infrastructure built on top of Hadoop. IT provides tools to enable easy data ETL, a mechanism to put structures on the data, and the capability to querying and a Nalysis of large data sets stored in Hadoop files. Hive defines a simple sql-like query language, called QL, which enables users familiar with SQL to query the data. At the same t

that simply transfers an element of add/offer operation directly to the Remove/take operation. In other words, it does not cache any elements in itself, so it is not a real queue in the strict sense. This queue maintains a list of threads that wait for elements to be added or removed from the queue. Simply put, there is at least one remove/take operation when the Add/offer operation succeeds, and at least one add/offer operation is remove/take operation to succeed. This is a two-way waiting que
