Doris streamload task reported an error connection reset [How to Solve]

Background

The spark program scans a hive table (size 3-7g), and then submits the streamload task of HTTP protocol to the Doris cluster. After the Doris cluster is upgraded from 0.13.15 to 0.14.12, the Spark Program suddenly reports an error streamload, and a connection reset occurs

analysis

enable_ http_ server_ V2
this parameter can be viewed by referring to the Fe Chinese configuration. It is used to determine whether to open a new style interface for the Doris interface, but in fact it has more than that. Please continue

New and old versions for Enable_ http_ server_ The default value of V2 parameter is different

In 0.13.15, the default value is false, that is, the default interface is the style of the old version, and the UI is older.

0.14.12 on the contrary, the default value is true, that is, the default interface opens a new style and new UI interface, but there will be problems at the same time
according to the analysis of the source code (palofe. Java), HTTP V2 does not limit the file size uploaded by HTTP, so the default value in springboot will be used to limit it, and the problem of connection reset will appear in the appearance.

Solution:

Method 1: close this parameter and the task can run normally

Method 2: I originally wanted to fix this problem. After looking at the community, I found that a doris-6013 was just merged two days ago, which is exactly the problem. I need to make a patch. However, note that there is a problem with this PR, and the unit is wrong. I need to make a patch together with doris-6070 to fix it.
these two PR mainly add two parameters to httpv2 in the new version of Doris

spring.servlet.multipart.max-file-size=100M
spring.servlet.multipart.max-request-size=100MB
max-file-size is the individual file size
max-request-size is to set the total uploaded data size

If you want to not limit the size of file upload, set both values to – 1. I didn’t test this – 1, but it should work. I will comment on this blog after I test it or confirm with the proposer of PR

Key supplement

After testing, it is found that the above two parameters have no effect. Refer to the community issue-6149
this patch to fix this problem

[SpringBoot] Maven Error: Connection refused to host: 127.0.0.1

This error occurred during package guide today:

java.util.concurrent.ExecutionException: java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection timed out: connect

After checking, the reason is that the JDK version used in the project is different from that imported by Maven. Put Maven – & gt; Just change the JDK importer version in importing to the project version.

For example, I use 1.8, so I change it to:

It’s done~

[Solved] SpringMVC Run Error: SEVERE-Servlet.service() for servlet jsp threw exception

Today, I was learning spring MVC. Everything was difficult at the beginning. I didn’t expect it to be so difficult. The most basic Hello World was trapped for half an hour. The main problem was that Tomcat 10 version didn’t adapt to and Maven relied on. The error was: servlet. Service () for servlet JSP thread exception Java. Lang. NullPointerException , and the following is the specific solution

Read the original text

At the beginning of writing dependency, I found that groupid in the book was javax , and I had suffered such a loss before. In order to adapt it to my Tomcat 10, I changed it to Jakarta . As a result, when writing controller , the method can only recognize javax , and I can’t change the source code again, There is no way to replace dependence with this

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.1</version>
</dependency>
<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>javax.servlet.jsp-api</artifactId>
    <version>2.3.3</version>
</dependency>

Not surprisingly, when the Tomcat server is executed, it always reports an error saying that org.springframework.web.servlet.dispatcherservlet in the configuration file is not a servlet, so there is no way but to change the method

I thought Maven could play Tomcat plug-in and paste the dependent code immediately

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
        </plugin>
    </plugins>
</build>

Continue to run and report an error: servlet. Service () for servlet JSP thread exception Java. Lang. NullPointerException , go to stackoverflow and say that the range must be set to provided , and then run to display it. Later, switch back to normal tomcat operation with a try state, but the result is still not good

PS: finally switched back to Tomcat version 9.052

Mac compiles Doris with MVN and reports an error checkstyle

At present, it is judged that the plug-in I commented out reported an error.

[Solved] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install (default-cli) on

This problem bothered me for a while. What I want to say is that I couldn’t find the problem when deploying springboot through Maven. Therefore, after quickly arranging a springboot project, I found that the error will still be reported

When Maven hits the jar package, an error is reported when executing install, and the symbol cannot be found in a line

Record the problems encountered:

Since the problem has been solved before posting, there is no picture, please watch and think patiently!

Today, when preparing to deploy a project with a jar package, an error is reported in install. According to the idea prompt, it is locked in a line of a class

According to the error prompt, I found that I created a new class in package B, and the jar package I am typing is package a,

1. So I checked pom.xml in project a to see if the dependency of package B was introduced. It was confirmed that it had been introduced

2. I thought it might be that I didn’t print jar package for project B, so I tried to package project B first and then print package a

IDEA springboot can recognize POM files, but suddenly it can’t reference mven dependencies. Strange things, inexplicable solutions

Foreword: today I open idea 2020.3 and find that all the spring boot projects can’t find all the dependencies. These projects were started normally yesterday

then I subconsciously thought that my Maven settings were wrong, but I checked and found that there was no problem with Maven configuration, and idea also recognized the pom.xml file. After reloading Maven dependencies several times, it still couldn’t work. Emmmmm, I think it may be caused by idea cache, right?The entire project was reloaded, but still not. Then I went to Baidu. There were not many solutions on Baidu and what I did above. I put on a mask of pain. I’m just a rookie. How can I meet this kind of thing?T.T.

Suddenly, I noticed that the red dot of idea event log was flashing, and I click to see

It said that there was something wrong with my plug-in, emmmmm. I don’t know why it suddenly went wrong, so I unloaded the plug-in, restarted the idea, and returned to normal. My God, what’s the situation?
