Using vscode’s own git interface to operate pull, there may be an error about the tag would clobber existing tag, resulting in the inability to pull
Solution:
1. Type git pull directly in terminal to finish pulling the code. Although the code is pulled, the vscode git tool still does not work.
2. Type git fetch –tags -f in terminal to force the local code tag to be updated first. Then use vscode’s git tools to pull the code.
Question:
ERROR: Attempting to operate on hdfs namenode as root
ERROR: but there is no HDFS_NAMENODE_USER defined. Aborting operation
Solution:
Look for the start-dfs.sh and stop-dfs.sh files in the /hadoop/sbin path, and add both to the top of them:
#!/usr/bin/env bash
HDFS_DATANODE_USER=root
HADOOP_SECURE_DN_USER=hdfs
HDFS_NAMENODE_USER=root
HDFS_SECONDARYNAMENODE_USER=root
By the way, at the top of the start-yarn.sh and stop-yarn.sh files, add:
#!/usr/bin/env bash
YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root
The error contents are as follows:

Cause of problem:
Because my spring cloud version is too high, I lack related dependencies.
Solution:
Add the following dependencies to the spring cloud configuration center client POM file:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
<version>3.1.0</version>
</dependency>
To illustrate, my spring cloud is version 2020.0.1, and the above dependencies should be added above the spring cloud g version.
ERROR! A malformed block was encountered while loading a block
[root@ansible test]# ansible-playbook -C roles_redis.yml -i hosts
ERROR! A malformed block was encountered while loading a block
Reason:
You don’t add the follow code after include when you are write main file:
- include add_group.yml
Solution:
We must pay attention to the problem of space format. The specification is very strict
- include: add_group.yml
E200033：
cd .svn
mv wc.db wc.db.old
splite3 wc.db.old
sqlite> .backup main wc.db
sqlite> .exit
cd ..
svn cleanup
1. Enter the SVN root hidden folder Svn
2. Backup database
3. SQLite opens/displays database
4. Back up the new database main to complete database replication
5. Exit SQLite
6. Return to SVN root
7. SVN cleanup
Usually this error is a signature error
This figure is the case given by wechat. The signature is MD5. Note that there is no colon here. Check whether there is more colon
For example:
MD5: 01:B3:DF:B0:8F:AB:39:07:A2:F7:F3:CF:54:F0:1E:C9
Then I fill in:
01B3DFB08FAB3907A2F7F3CF54F01EC9
It’s easy to make mistakes here. I write it down here. I hope it can help you!
As for signature acquisition: Click gradle on the far right of Android studio, select singreport, double-click, and you can see it in build,
By the way, if you want to build Signature files are configured under gradle (APP)
First, state that there are several reasons for this error
Here are my personal solutions to this error:
1. First, find gradle Properties file, open
2. Write “Android” in the space After enableaapt2 = false, click sync now
3. Errors will occur after synchronization. Don’t worry. Delete what you wrote and synchronize again
There is no problem running after resynchronization (personal situation)
The stdint.h file is a standard header file for C99, which is not supported by vs2008 by default, so you will definitely encounter the problem of “No such file or directory” in the process of using it.
Solution: Download stdint.h or make a copy from vs2010 and put it under Program Files (x86)\Microsoft Visual Studio 9.0\VC\include path
After installation, the jumpserver selects a custom port, and the HTTP port 80 is changed to 88. After forwarding through nginx, remember to set the upgrade of nginx, otherwise it will prompt: connect websocket server error
Nginx is configured as follows:
##Jump
server {
listen 80;
server_name jump.xxxxxx.cn;
location/{
proxy_pass http://127.0.0.1:88;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}This will not prompt an error
Win10 installation software Report
The installer has encounteredan unexpected error
installing this package.This may indicate a problem with this package.The error code is 2503.Solution:
Open cmd with administrator privileges and enter the command
msiexec /package C:\Users\asus\Downloads\TortoiseSVN-1.14.1.29085-x64-svn-1.14.1.msi
Where msiexec /package is followed by the path of your installer, and the download is successful after pressing Enter.
Problem description
If the tag and heads have the same name, an error will be reported
error: dst refspec v0. 10.2 matches more than one
Problem analysis
refs/heads/* is the branch name refs/tags/* is the tag name refs/remotes/* is the remote track name
When naming heads, it generally uses main, master, that is refs/heads/Master, refs/heads/main
when naming tags, it usually uses v0.1, v0. 2, i.e. refs/tags/v1.0
When you execute git push origin master, because Master is generally only in heads, not in tags, GIT can directly find the branch you want to push.
But here:
git LS remote the results are as follows:
61d10100326130d2eceee85167d5ec2d9970ebbe refs/heads/seq_task
4ee9724f3a6a47134483e4955c688f4f34432ee0 refs/heads/simulastsharedtask
83e615d66905b8ca7483122a37da1a85f13f4b8e refs/heads/v0.10.2
bdf09e1321a77252835550e84d73ad1bb3f3173c refs/heads/xlmr_benchmark
3e5a2739bce92b2516d060959a1aa3dd51d221dc refs/tags/v0.10.0
8a0b56efeecba6941c1c0e81a3b86f0a219e6653 refs/tags/v0.10.1
83e615d66905b8ca7483122a37da1a85f13f4b8e refs/tags/v0.10.2
Twice v0.10.2 , corresponding to tags and heads respectively, so an error is reported.
Solution:
git push origin refs/heads/Main: refs/tags/V1 with the full name of the branch 2

JRE 1.8.0_242-release-1644-b01 amd64 by JetBrains s.r.o
D:\soft\Android_Studio\jre\jre
Solution:
View the mentioned directory C:\users\{user}\appdata\roaming\Google\androidstudio4.1\plugins found two different versions
tried to back up the lower version 4.1, and deleted the problem. The corresponding 4.1 results were generated again. Refer to the search results and delete the files under plugins. Still not resolved
try backup and delete the plugins file under 4.2. Still not resolved
restore the original file. Find the directory where the as software is installed and check whether the problem is caused by the plug-in provided by the as. First backup, then delete, and start as. The results are as follows 
. I have 50 plug-in files. Copy the first 25 first
it seems that some necessary documents are needed Copy the java related plug-ins into it
copy the relevant plug-ins according to the prompts. (the corresponding plug-in is not found) continue to try, move in all the rest, and report the initial error. Therefore, find the plug-in excluded from use, and then delete it. But there is still a lack of plug-ins org.jetbrains.android search problem, but the corresponding disabled cannot be found locally_plugins.txt go back to the problem and find it on stackoverflow
Finally, bow to reality and reload Dafa.
However, it still can’t start. Download the latest version
