kandi X-RAY | json-io Summary

json-io is a Groovy library typically used in Utilities, JSON Processing applications. json-io has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Perfect Java serialization to and from JSON format (available on [Maven Central] To include in your project:. json-io does not require that Java classes implement Serializable or Externalizable to be serialized, unlike the JDK’s ObjectInputStream / ObjectOutputStream. It will serialize any Java object graph into JSON and retain complete graph semantics / shape and object types. This includes supporting private fields, private inner classes (static or non-static), of any depth. It also includes handling cyclic references. Objects do not need to have public constructors to be serialized. The output JSON will not include transient fields, identical to the ObjectOutputStream behavior. json-io does not depend on any 3rd party libraries, has extensive support for Java Generics, and allows extensive customization.

Reading an array in json-io: Object cannot be cast to List

java.lang.ClassCastException: class [Ljava.lang.Object; cannot be cast to class java.util.List

Note that [Ljava.lang.Object represents the array type for object arrays, so it is Object[]. Since json arrays can contain anything, i.e. strings, booleans, numbers, objects or arrays, and in any combination any JSON parser would have 3 options:

Use Object as the array's element type. This would then result in Object[] as in your case.
Use some array element type provided by the user, i.e. if you know the array will contain only strings then you'd tell the parser that it should produce a String[] result. If the array contains anything other than strings that would most likely fail though.
A sophisticated parser might first collect the elements, determine their types and try to use the most special common types (if all elements are strings that would be String). However, the API can't reflect that because the compiler doesn't know what the json will contain at runtime. Hence the API could only use the first two options (an in many libraries like Jackon or Gson both are present) so the user would then have to cast either the array or the elements themselves and in that case there's little to be gained to make the parser that sophisticated.

Now you probably ask why the parser returns a Object[] instead of List. That's a decision made by the designer(s) of that library and I can only guess what the reasons are. However, json itself only knows arrays so the logical consequence would be to use Java arrays as well if no other type information is provided.

QUESTION

Live nodes shows one node while Data nodes are up in Hadoop 2.9

Asked 2019-Mar-17 at 06:14

I created a Hadoop cluster with 1 master and 2 slaves. All of the services are running in nodes. Datanode and Nodemanager are active on slave1 and slave2. Namenode, Datanode, Nodemanager, ResourceManager, and SecondaryNameNode are active on the master. But the Web UI of NameNode (localhost:50070) in part of Live nodes shows 1 node (master) and the web UI of yarn shows 1 active node.

The following works are done:

Disable firewall.
Password-less ssh connection between all of the nodes.
Hostname configuration.
Transfer Hadoop config files from master to slaves.

how to solve this problem?

I found the solution. By checking the log, I understood the problem there is because of the wrong definition of hostnames. They should be defined as FQDN. And also to remove the error:

Retrying connect to server: localhost/127.0.0.1:9000

should remove the line with 127.0.1.1 address from all hosts, Otherwise, it's only listening on that local address, not the external one. As blew:
