[easy to fix list] good for new contributors

[casionone]

The following list is the latest newbie tasks (keep up to date). If you are participating in an open source project for the first time, it is recommended to choose one of the following tasks to practice. The first task is used to familiarize yourself with the submission process and feel the friendliness of the community. If you are interested in a task, Please leave a message, for example, I am interested in implementing this task, please submit a PR in 2 weeks if you leave the message. If more than 2 weeks, other contributors are welcome to do it.

😊 The current development branch is master please submit pr to this branch

For the claim of the issue task:

At present, github cannot directly assign issues to those who do not have permission to write the project repository. Only allow issues to be assigned to people who have commented on the issue. https://github.blog/2019-06-25-assign-issues-to-issue-commenters/

😊 For students who want to claim the linkis issue task and do not have warehouse write permission, they can comment under the corresponding issue. Then the administrator can assign it to you

以下是新手任务列表（持续更新中）。如果您是第一次参加开源项目，建议您选择以下任务之一进行练习。第一项任务是熟悉提交过程，感受社区的友好。如果您对某项任务感兴趣，请留言，例如，我对执行此任务感兴趣，如果您留言，请在2周内提交PR。如果超过2周，欢迎其他贡献者参与。如果有任何问题可以在下方留言，解决issue过程中的任何开发或者其他问题，社区同学会协助解决。

😊 当前开发分支为master，请提交pr至此分支

对于issue任务的认领:

目前github对于没有项目仓库写权限的人员，没法直接分配issue。只允许将issue分配给在该issue下评论过的人。 https://github.blog/2019-06-25-assign-issues-to-issue-commenters/

😊 对于想认领linkis的issue任务，又没有仓库写权限的同学，可以在【对应的issue下】评论（如:I want to fix this issues，you can assign it to me）， 然后管理员就可以分配指定给你

Hi, we think the code styles issues would be helpful for the beginner to be familiar with the PR workflow. If you find some content satisfying the following rules, welcome to submit PRs.

Code styles can be improved:

• typo in classes/methods/fields/comments
• redundant code, such as commented code, unused class/methods/fields
• duplicated code snippet, extract the duplicated code for reusing
• refactor, maybe some best practice
