Solution:
sudo apt-get install python3.6-devIt may be due to the mismatch of dev version due to the installation of Python 3.6 in Ubuntu.

How to Solve:
This is because the custom entity class does not implement the WritableComparable<Commodity> interface, or does not override the compareTo method, resulting in a class conversion exception due to lack of serialization.
There is another possibility that
Implementing the WritableComparable<Commodity> interface instead of the WritableComparable<Commodity> interface because of the mapreducer rules
This implementation of two interfaces will result in the above error message when using a custom entity class for the value without problems, but when using a custom entity class for the key
Just reimplement the WritableComparable<Commodity> interface and guide the package
Hadoop specifies that if you implement the Writable and Comparable<Commodity> interfaces, the data of the custom entity class can only be used as value, but if you implement the WritableComparable<Commodity> interface, the data of the custom entity class can be used as both key and value.
The development of a C/s project involves the problem of regular reconnection of the client after the server is stopped. During the development process, an error is reported as follows:
After the socket is disconnected, it can only be reconnected asynchronously, and can only be connected to different endpoints. Beginconnect must be called on the thread that will not exit before the operation is completed.
After searching for relevant information on the Internet, the problem was not solved. A whim occurred and the universal list type was used to solve the problem. The methods are as follows:
Add global variables first
Private _Socket As New List(Of Socket)Add several more in the process of connection_ Socket.Clear()：
Private Sub ConnectServer()
_Socket.Clear()
Dim SockClient As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
_Socket.Add(SockClient)
Dim Address As IPAddress = IPAddress.Parse(_ServerIPString)
Dim Endpoint As New IPEndPoint(Address, _ServerPort)
Try 'Catching exceptions
_Socket(0).Connect(Endpoint) 'initiate the connection, where the first index in the List is used instead of the local SockClient
Catch ss As SocketException
Dim strErrorMsg As String = ss.SocketErrorCode.ToString
strErrorMsg = strErrorMsg.Replace("TimedOut", "Connection timeout!")
strErrorMsg = strErrorMsg.Replace("ConnectionRefused", "Connection rejected!")
If SockClient.Connected Then SockClient.Close()
_Socket.Clear()
MessageBox.Show(strErrorMsg, "Connection exception", MessageBoxButtons.OK, MessageBoxIcon.Information)
Return
Catch s As Exception
If SockClient.Connected Then SockClient.Close()
_Socket.Clear()
MessageBox.Show(s.Message, "exception", MessageBoxButtons.OK, MessageBoxIcon.Information)
Return
End Try
End Subbe accomplished
Test results:
After repeatedly disconnecting the server, call the connectserver process again to connect again. The connection is successful and no error is reported.

Done!
There was a problem with the gadget made before. From time to time, it reported that the array exceeded the boundary, but the specific code could not be located.
Take some time to solve it today.
The effect you want to achieve is like this: multiple threads display messages on the textarea in turn. In order to ensure real-time data update, you need to constantly refresh the textarea component.
The original code is like this
public void refresh() {
if(currentServerName == null) {
//Refuse to refresh
return;
}
setText("");
appendText(LOG_MAP.getOrDefault(currentServerName, ""));
setScrollTop(Double.MAX_VALUE);
}Directly refresh the data in the textarea in an external thread (a thread created by yourself).
After consulting the data, it is found that the container content must be modified in JavaFX’s own thread to ensure that no error will be reported. So wrap it with the platform. The modified code is as follows:
public void refresh() {
if(currentServerName == null) {
//Refuse to refresh
return;
}
setText("");
appendText(LOG_MAP.getOrDefault(currentServerName, ""));
setScrollTop(Double.MAX_VALUE);
Platform.runLater(()->{
setText("");
appendText(LOG_MAP.getOrDefault(currentServerName, ""));
setScrollTop(Double.MAX_VALUE);
});
}Add in entry file
//Allowed source domains
header("Access-Control-Allow-Origin: *");
//Allowed request header information
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");
//Allowed request types
header('Access-Control-Allow-Methods: GET, POST, PUT,DELETE,OPTIONS,PATCH');In M1 series chips, the MAC uses CONDA to switch the environment in order to directly install various libraries or other operations in the target environment. Otherwise, it is directly installed in the python environment in miniforge 3, rather than the python environment being used.
(if CONDA install package_name reports that the permission is not enough, it may be because sudo bash miniforge 3… SH is used when installing miniforge 3, that is, it is installed with the administrator’s permission) — the author’s machine is installed with sudo bash miniforge 3… Sh. here is only a record of the pit he stepped on. Using sudo CONDA install package_Name can solve the problem.
Problems encountered in configuring Python environment on macbook pro of m1pro chip:
After configuring CONDA’s Python environment, switch the environment to use
conda activate env_name #如 conda activate py39
Errors are reported as follows:
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'
Solution:
Input directly at the terminal:
conda init zsh
Exit the Mac’s Zsh shell and restart. Then execute CONDA activate env_ Name.
Note: exit the current environment:
conda deactivate

How to Solve:
After ES re extracts the data, the data of one field becomes particularly large, resulting in a particularly large package when returning to the front end, resulting in too large response data of nginx. Temporary files will be used for processing, but the user does not have the permission to operate this directory, so the service is stopped directly. Finally throw the above error.
Solution:
1. Check the error log of nginx (/data/000x/nginx/logs/error.Log)
2021/12/01 12:05:40 [crit] 66289#0: *680 open() "/data/000x/nginx/proxy_temp/2/02/0000000022" failed (13: Permission denied) while reading upstream, client: 192.16.199.1, server: localhost, request: "POST /api/search/result HTTP/1.1", upstream: "http://127.0.0.1:17803/search/result", host: "192.16.199.20:17002", referrer: "http://192.16.199.20:17002/pc/"
2. To/data/000x/nginx/proxy_Temp grant permission
Done!!!

Reason & Solution:
It’s the version problem
Just contacted idea, downloaded the version of 2020.3, created the web version is 5.0, when creating the project can not be modified to reduce the version, and jdk configuration of 1.7, tomcat with 7, so it reported this error. Later, jdk was changed to 1.8 and tomcat was changed to 9 and started normally.
And then continue to reproduce the problem, left for the record, found that only the impact of jdk, jdk1.8 with tomcat7 can also start the project normally.
The long time to do have a love of the old plot, jdk1.7 has been used to the present, too lazy to replace, so ignore the version of the problem.

Node.js v17.1.0
Solution:
The reason for the problem is that OpenSSL has been updated in node.js V17
the solutions are:
1. Solve temporarily and set environment variables
#windows
set NODE_OPTIONS=--openssl-legacy-provider
#linux
export NODE_OPTIONS=--openssl-legacy-provider
2. Lower the version of node.js instead of V17
