The difference between the navigation controller and the view controller in adding controllers1.Because the navigation controller has a navigation stack, there is an array viewcontrollers that the normal view controller does not have, and the view controller that joins the a

Value transfer from the IOS navigation controller to the ios navigation Controller UINavigationController is the main tool used to build layered applications. It uses stacks to implement views. Any type of view controller can be put into the stack. When designing the navigation controller, you must specify the root vie

What is HiveTurn from: 791026911. Hive IntroductionHive is a data warehouse infrastructure built on Hadoop. It provides a range of tools that can be used for data extraction conversion loading (ETL), a mechanism that can store, query, and analyze large-scale data stored in Hadoop. Hive defines a simple class-SQL query language called HQL, which allows the user who is familiar with SQL to query data. At the

Hive learning Roadmap The hadoop family articles mainly introduce hadoop family products. Common projects include hadoop, hive, pig, hbase, sqoop, mahout, Zookeeper, Avro, ambari, chukwa, new projects include yarn, hcatalog, oozie, Cassandra, hamr, whirr, flume, bigtop, crunch, and hue. Since 2011, China has entered the age of big data. Family software represented by hadoop occupies a vast territory of big

family The entire Hadoop consists of the following subprojects: Member name use Hadoop Common A low-level module of the Hadoop system that provides various tools for Hadoop subprojects, such as configuration files and log operations. Avro Avro is the RPC project hosted by Doug Cutting, a bit like Google's Protobuf and Facebook's thrift. Avro is used to do later RPC of Hadoop, make Hadoop RPC module communicate faster, data structure is more compact 。 Chukwa Chukwa is a large cluster monitorin
