[DISCUSS]Discussion of some problems encountered in the process of deploying Linkis

[binbincheng <74...@qq.com.INVALID>]

Wechat group "Apache Linkis community Development group " chat records are as follows:


Barbarossa:
Hello everyone, when I deployed Linkis for the first time, linkis-ps-publicservice.log printed out the error "The first upload of the resource failed". How can I solve it? I use hadoop3.3.1, linkis1.3.1, hive3.3.1


Xia Chen:
Is it adapted according to the official website process?


Barbarossa:
hmm, yes


Xia Chen:
See if there is any abnormal information in the ps-publicservice log


speechless:
Have you used the flink engine?


Xia Chen:
https://github.com/apache/linkis/issues/4260 Is this the problem?


Barbarossa:
Yes, I just wanted to take a screenshot. This is the question I posted last night?


Barbarossa:
I modified the flink version according to the process, but it was not enabled


speechless:
Verified that there are not a bunch of mistakes, tuned one by one


Change!! (Intellect):
Permissions issue


Change!! (Intellect):
It seems to be hdfs


Barbarossa:
Is linkis the authority to call HDFS?


Barbarossa:
I tested that HDFS can be uploaded separately, and linkis can also create folders on HDFS during installation.


Mr. Lightning:
You can look up related information on the Internet


Mr. Lightning:
It is that hdfs is not working properly, and the command line interface is different from the java interface.


Barbarossa:
My installation user and user user are the same


Numbly:
This installation refers to the user who executes the install script?


Barbarossa:
Yes, that's how I understand it



Change!! (Intellect):
I have installed it a few times, and every time I encounter it, it should be solved by modifying the permissions or owner in hdfs.


Barbarossa:
I'll test it

微信群“Apache Linkis社区开发群”聊天记录
如下面所述：



巴巴罗萨：
大家好，我在第一次部署Linkis的时候linkis-ps-publicservice.log打印出“The first upload of the resource failed”的错误。请问我该如何解决？我这用的是hadoop3.3.1、linkis1.3.1、hive3.3.1


夏晨：
是按官网流程进行的适配吗？


巴巴罗萨：
嗯嗯，对的


夏晨：
看下ps-publicservice日志下有没有异常信息


无言：
有没有用了flink引擎的


夏晨：
https://github.com/apache/linkis/issues/4260 是这个问题吗？


巴巴罗萨：
对对，我刚想去截图，这个就是我昨晚发的问题？


巴巴罗萨：
我按照流程修改了flink版本，但没有启用


无言：
验证了没有   一堆错 一个个调

Change!!（智纲）：
权限问题


Change!!（智纲）：
好像是hdfs的


巴巴罗萨：
linkis调用HDFS的权限吗？


巴巴罗萨：
我单独测试了HDFS是可以上传的，linkis在安装的时候也是能在HDFS上创建文件夹。


闪电先生：
这个问题可以看看上网查查相关资料


闪电先生：
是hdfs工作不正常，命令行接口和java接口不一样。


巴巴罗萨：
我的安装用户和使用用户是一致的


木然：
这个安装 指的是执行 install  脚本的用户？


巴巴罗萨：
对的，我是这样理解的


Change!!（智纲）：
我安装过几次，每次都会碰到，应该都是通过修改hdfs里头的权限或者owner解决的。


巴巴罗萨：
我测试一下
