使用 Ansible 下载 hadoop-3.2.2.tar.gz 文件后出现校验和错误

Question

我使用以下 Ansible 代码下载了 hadoop-3.2.2.tar.gz 并检查了文件。当然，这是Hadoop官方主页。

---
- hosts: all
  remote_user: root
  tasks:
  - name: Download file with checksum url (sha256)
    get_url:
      url: https://downloads.apache.org/hadoop/common/hadoop-3.2.2/hadoop-3.2.2.tar.gz
      dest: ~/hadoop-3.2.2.tar.gz
      checksum: sha256:https://downloads.apache.org/hadoop/common/hadoop-3.2.2/hadoop-3.2.2.tar.gz.sha512

但是出现了以下错误：

TASK [Download file with checksum url (sha256)] **********************************************************************************************
[WARNING]: File '/home/pi/hadoop-3.2.2.tar.gz' created with default permissions '666'. The previous default was '666'. Specify 'mode' to

这是否意味着 hadoop-3.2.2.tar.gz 已被破坏，或者代码有问题？

Answer 1

您正在下载 sha512 校验和，但指定 sha256。所以 ansible 期望错误的校验和，因此验证失败。

这应该有效：

checksum: sha512:https://downloads.apache.org/hadoop/common/hadoop-3.2.2/hadoop-3.2.2.tar.gz.sha512
