information /hbase/root-region-server contains the machine name of the region server where the-root-region is located, which is often used in area targeting /hbase/rs This znode is the root node for all region servers, and the cluster is used to track server exceptions, each znode is a temporary node, and the node name is the name of the region server /hbase/shutdown This node is used to track cluster status information, including the time of cluster startup and the empty state when

A stream is a series of data items that generate only one item at a time.Java 8 new Programming Concepts: Stream processing, passing code through APIs, functional programming.:: Syntax: "Use this method as a value".Functional Programming Style: write the function as an equivalent program.predicate (predicate): The predicate accepts a parameter value and returns TRUE or false.

Step 5: test the spark IDE development environment The following error message is displayed when we directly select sparkpi and run it: The prompt shows that the master machine running spark cannot be found. In this case, you need to configure the sparkpi execution environment: Select Edit configurations to go to the configuration page: In program arguments, enter "local ": This configuration indicates that our program runs in local mode and is saved after configuration.

Chapter 8. Introduction to multi-project builds multi-project construction Introduction, openbuilds Only the smallest of projects has a single build file and source tree, unless it happens to be a massive, monolithic application. it's often much easier to digest and understand a project that has been split into smaller, inter-dependent modules. the word "inter-dependent" is important, though, and is why you

method receives a consumer function interface that is called if the value exists, so if you want to print the value simply, you can:optional.ifPresent(System.out::println);If the value exists, nothing will happen.The Flatmapfang method applies a mapping method and returns a value that is described by a optional, more than that, which can be called by cascading, as follows to check for a series of NULL cases:Company1.flatmap (company::getoffice). FlatMap (office::getaddress). flatM
