Cannot start container 39f96c64a9c6: [8] System error: exec format error

An error occurred when Docker started the container!

Error response from daemon: Cannot start container 39f96c64a9c6: [8] System error: exec format error
FATA[0000] Error: failed to start one or more containers

Cause: Running a 64 bit Docker image on a 32-bit system

To view the system version:

  • uname -a
  • lsb_release -a

Solution:

Install and use docker in Ubuntu 14.04 (32-bit)

New Error as below:

FATA[0000] Post http:///var/run/docker.sock/v1.18/images/create?fromSrc=ubuntu%3A14.04&repo=: dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?

Solution: Switch to root administrator status to solve the problem!

[Solved] Internal Error: EPERM: operation not permitted, open

When installing yarn on nodejs (my version: 16.17), after executing the command: corepack enable, I got an error: Internal Error: EPERM: operation not permitted, open 'Y:\nodejs-v16.17.0-x64\pnpm, The operation is not allowed, I thought of the previous execution of rm -rf /* with linux normal user will also prompt not allowed to execute the operation, and change to root (administrator) account to have higher privileges to execute the command, so I guess it should be the same problem, so I tried to run the cmd command window as administrator, and execute the command: corepack enable again, it succeeded It worked:

How to Solve Svn upload so File Error

Cause of the problem: since the so file is a binary file, it is ignored by default. You need to modify the configuration before uploading

Solution:

find   / -name .subversion # find SVN configuration file path

cd to find the path of .subversion

VIM config finds these two lines:

#global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *pyo

#  *.rej *~#*# .#* .*.swp.DS_Store

Modified as:

###global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *pyo

###  *.rej *~#*# .#* .*.swp.DS_Store

global-ignores = .*.swp.DS_Store

It can be solved after saving!

[Solved] vue watch Error: Error in callback for watcher “xxx“: “TypeError: Cannot read properties of undefined …

 

1. Question

1. Listening to an object in data, an error is reported. The error is strange: you cannot use the apply method on undefined

1) detailed errors are as follows:

vue.esm.js?9b69:5059 [Vue warn]: Error in callback for watcher "flowCategory": "TypeError: Cannot read properties of undefined (reading 'apply')"

globalHandleError @ vue.esm.js?9b69:3724
handleError @ vue.esm.js?9b69:3691
invokeWithErrorHandling @ vue.esm.js?9b6

2) the code is as follows:

  watch: {
    flowCategory: {
      hanlder(newval, oldval) {
        console.log('flowCategory', newval, oldval);
      },
      deep: true
    }
  }

2. Solution:

After searching for a long time, I found that I had written the word “handler” incorrectly. I typed it incorrectly and wrote it as “hanlder”, and the IDE did not prompt  &***&;

Change it to the following. That’s all

  watch: {
    flowCategory: {
      handler(newval, oldval) {
        console.log('flowCategory', newval, oldval);
      },
      deep: true
    }
  }

3. Now we finally understand the error reporting: it is to tell us that the handler has a problem. The watch does not know what to do when monitoring changes.

Disabling Document Server Access Authentication
Next, disable access authentication for Document Server, which by default rejects unauthenticated requests (i.e., self-signed HTTPS requests).

I am now running Document Server with Docker, using the docker exec command to log into the container.

There seems to be only the nano editor in the container, but that’s enough.

Open /etc/onlyoffice/documentserver/default.json, go down and find the rejectUnauthorized field and change its value to false.

Restart the container.
Modify default.json

Cause analysis:

When I first saw this error report, I guessed that the bean was not successfully created. I also searched various answers on the Internet. Some said that @ service might not be added to the service layer. I looked at it for no reason, so I began to read the error information

Look directly at the error reported in the first line, because the first line is likely to be the main reason for the error:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'baseMapper'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userMapper' defined in file [E:\IDEA Project\demo\target\classes\com\example\demo\mapper\UserMapper.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [com/baomidou/mybatisplus/autoconfigure/MybatisPlusAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [E:\IDEA Project\demo\target\classes\mapper\VersionMapper.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. The XML location is 'file [E:\IDEA Project\demo\target\classes\mapper\VersionMapper.xml]'. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'com.libv.entity.Version'.  Cause: java.lang.ClassNotFoundException: Cannot find class: com.libv.entity.Version

I’ll take this long paragraph wrong and look at it in pieces
at first, I thought it was the problem of userController, then carefully check whether it was not, and then look back:

nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl'

I went to see userServiceImpl again and didn’t find any problems, so I was wondering if I understood the error in this paragraph, so I searched the meaning of nest. It turned out that there was nesting besides nesting! That is to say, the error reporting in this paragraph is actually an exception nested with another exception ! In other words, it is the innermost error that causes the error of each layer above, thus throwing an exception! So I went straight to the back part:

nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. The XML location is 'file [E:\IDEA Project\demo\target\classes\mapper\VersionMapper.xml]'. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'com.libv.entity.Version'.  Cause: java.lang.ClassNotFoundException: Cannot find class: com.libv.entity.Version

Found to be VersionMapper.xml has a problem because of Error resolving class, That is to say, there is a problem with one class. Look at the last: Cannot find class: com.libv.entity.Version.
I went to see XML again:

<mapper namespace="com.libv.mapper.VersionMapper">
    <insert id="release" parameterType="com.libv.entity.Version">
        insert into version(id,version,download_url,release_time)
        values (#{id},#{version},#{downloadUrl},NOW())
    </insert>
</mapper>

Now I understand, because I don’t have com.libv.entity this bag! That is, the wrong path of my Version class leads to errors in XML, resulting in layer-by-layer exceptions.

Solution:

Change the directory path of the corresponding class of parameterType in XML

<mapper namespace="com.example.demo.mapper.VersionMapper">
    <insert id="release" parameterType="com.example.demo.Entity.Version">
        insert into version(id,version,download_url,release_time)
        values (#{id},#{version},#{downloadUrl},NOW())
    </insert>
</mapper>

Run again, success!

In this case, I can’t wait all the time. I waited for a while and didn’t initialize well…

Solution

Because it is a new cluster, there is no useful data. You can clear the metadata in the following way to reinitialize. Before clearing metadata, close HBase components in USDP’s Web UI.

Delete ZK’s metadata

Since part of the metadata of HBase is stored on zookeeper, so you should so this as below:

HDFS metadata deletion

Since part of HBase data is stored in HDFS, it is also necessary to delete the metadata stored in HDFS by HBase. Since USDP has Ranger and actually has users and permissions, you can’t use root to delete important data of HDFS. You must switch to Hadoop user first.
