Command failed after 1 tries

一、问题现象概览

在 Ambari 调度安装 Hue（Bigtop 3.2.0） 过程中，执行到以下步骤时失败：

/usr/bigtop/current/hue/build/env/bin/hue syncdb --noinput

Ambari Agent 日志中显示命令返回码为 1，并伴随多段异常堆栈。

从表面看，最早出现的是一个 Django 命令不存在 的异常：

KeyError: 'syncdb'

但这并不是根因，而是 Python 运行时初始化阶段提前中断 导致的连锁表现。

二、完整异常链路拆解

一）第一层异常：Django 子命令加载失败

File ".../django/core/management/__init__.py", line 237, in fetch_command
  app_name = commands[subcommand]
KeyError: 'syncdb'

从 Django 角度看，这是：

• manage.py 启动正常
• 但 settings 尚未完整加载
• INSTALLED_APPS 未初始化完成

因此 Django 无法正确注册 syncdb 子命令。

二）第二层异常：settings.py 加载中断

继续向下看调用栈：

File ".../desktop/settings.py", line 38, in <module>
from aws.conf import is_enabled as is_s3_enabled

这一步表明：

• Hue 已进入 desktop 初始化阶段
• 并开始加载与 安全 / 云存储 / 身份代理 相关的模块

三）第三层异常：requests-kerberos 初始化失败

真正的关键错误出现在这里：

ImportError: libcom_err.so.3: cannot open shared object file: No such file or directory

随后紧跟着：

ModuleNotFoundError: No module named 'winkerberos'

这两个错误具有明确的指向性：

1. Hue 并未显式启用 Kerberos
2. 但 requests-kerberos 已被间接 import
3. requests-kerberos 在初始化时：

• 需要系统 Kerberos C 库
• 需要 Python Kerberos 绑定模块

三、为什么 Hue 会“被动”触发 Kerberos 依赖？

这是一个非常容易被忽略的点。

一）触发路径并非来自 HDFS 配置

在本场景中，并没有显式配置：

• WebHDFS Kerberos
• Hive Kerberos
• HDFS doAs Kerberos

但 Hue 在启动时，会统一加载：

• desktop.lib.idbroker
• aws.conf
• requests_kerberos.HTTPKerberosAuth

这是 设计行为，不是误配置。

二）requests-kerberos 的动态依赖机制

requests-kerberos 在 import 阶段的行为是：

1. 优先尝试加载：

• kerberos / pykerberos

2. 若失败：

• 尝试 winkerberos

3. 同时：

• 依赖系统层 Kerberos 动态库（libcom_err.so.*）

一旦 任一环节失败，整个 import 过程会抛异常，导致 Hue settings 加载失败。

四、根因总结（不是一个问题）

综合日志，可以明确这是一个 复合型问题：

层级	问题点
OS	缺失 libcom_err.so.3
系统库	Debian 系列仅提供 libcom_err.so.2
Python	requests-kerberos 版本与系统库不兼容
Hue	启动阶段未做 Kerberos import 兜底

所以 仅修 Python 包是不够的。

五、推荐修复方案（可复用）

一）补齐 Kerberos 运行时依赖（系统层）

优先确保以下依赖完整安装：

apt-get install -y \
  build-essential \
  gcc \
  python3-dev \
  krb5-config \
  krb5-user \
  libkrb5-dev \
  libkrb5-3 \
  libgssapi-krb5-2 \
  libk5crypto3 \
  libkrb5support0 \
  libcom-err2 \
  libsasl2-2 \
  libsasl2-modules \
  libsasl2-modules-gssapi-mit

二、解决 libcom_err 版本不兼容问题

在 Debian / Ubuntu 环境中：

• 实际存在的是：libcom_err.so.2
• requests-kerberos 期望的是：libcom_err.so.3

解决方式采用 软链接兼容：

sudo ln -sf /usr/lib/x86_64-linux-gnu/libcom_err.so.2 \
  /usr/lib/x86_64-linux-gnu/libcom_err.so.3

sudo ldconfig

这是运行时兼容方案，不影响系统原有库加载。

三、在 Hue 虚拟环境中重建 Python Kerberos 依赖

注意：必须使用 Hue 自身的 virtualenv。

sudo -u hue /usr/bigtop/current/hue/build/env/bin/pip install \
  --no-cache-dir \
  --only-binary=:all: \
  requests-kerberos==0.15.0 \
  pyspnego \
  cryptography \
  requests

随后，强制重装 Kerberos 绑定模块：

sudo -u hue /usr/bigtop/current/hue/build/env/bin/pip install \
  --no-cache-dir \
  --no-binary=kerberos,pykerberos \
  --force-reinstall \
  kerberos==1.3.1 \
  pykerberos==1.2.4

最后重启服务即可
