【Ambari开启Kerberos】- Atlas启动 - Hive服务检查异常处理

TTBIGDATA2025-11-20 11:39

一、问题背景

ttr-2.2.1 以上版本已修复

在 ttr-2.2.1 及以上版本中，Atlas 在开启 Kerberos 后会自动完成 Hive Hook 注入。

若使用早期版本（如 ttr-2.2.0 ），在 Service Check 环节可能因 Hive 未加载 Atlas Hook JAR 而失败。

如在部署或二开中遇到类似问题，可联系作者 获取补丁。
Atlas 启动/联动常见的四类权限或依赖问题

  1. HBase 无权限（AccessDeniedException）
  2. Solr 401 Unauthorized
  3. Kafka ACL 拒绝访问
  4. Hive 未正确加载 Atlas Hook（本文聚焦）

二、现象复盘与根因定位

1、错误堆栈（节选）

bash 复制代码 
stderr:

The above exception was the cause of the following exception:

2、核心结论

  • 触发点 ：Ambari 的 Hive Service Check 调用 hcatSmoke.sh，在 Hive CLI 启动时根据 hive.exec.post.hooks
    加载 Atlas HiveHook。
  • 根因 ：运行时 HIVE_AUX_JARS_PATH 未包含 atlas-hive-plugin 相关 JAR，导致 ClassNotFoundException:
    org.apache.atlas.hive.hook.HiveHook    。
  • 现象 ：kinit 成功、Hive 启动成功，但 Hook 初始化失败 → SQL 编译阶段报错 → Service Check 失败。

三、修复思路总览

  • 步骤一：为 Hive 注入 Atlas Hook 依赖 （修正 HIVE_AUX_JARS_PATH）
  • 步骤二：增强 hcat 服务检查脚本（在 Service Check 的执行环境中显式注入 Hook）

四、步骤一：为 Hive 注入 Atlas Hook JAR

目标：在 Hive CLI/服务 的运行环境中，始终能解析到 atlas-hive-plugin 依赖。

参考渲染后的 hive-env.sh 片段：

bash 复制代码 
ATLAS_HOOK_DIR="/usr/bigtop/current/atlas-server/hook/hive"

ATLAS_HOOK_JARS=$(
  {
    ls "${ATLAS_HOOK_DIR}"/*.jar 2>/dev/null
    ls "${ATLAS_HOOK_DIR}/atlas-hive-plugin-impl"/*.jar 2>/dev/null
  } | grep -v 'logback-classic' | tr '\n' ':' | sed 's/:$//'
)

if [ -n "${ATLAS_HOOK_JARS}" ]; then
  if [ -n "${HIVE_AUX_JARS_PATH:-}" ]; then
    export HIVE_AUX_JARS_PATH="${HIVE_AUX_JARS_PATH}:${ATLAS_HOOK_JARS}"
  else
    export HIVE_AUX_JARS_PATH="${ATLAS_HOOK_JARS}"
  fi
  # 规范化：去头尾冒号、合并重复
  export HIVE_AUX_JARS_PATH="$(echo "${HIVE_AUX_JARS_PATH}" | sed 's/^://;s/:$//;s/::\+/:/g')"
fi

说明

  • 自动扫描 Atlas Hook 目录，拼接为 HIVE_AUX_JARS_PATH；
  • 过滤 logback-classic，避免日志绑定冲突；
  • 规范化路径，防止多余冒号导致 classpath 解析异常。

五、步骤二：增强 hcat 服务检查脚本（显式注入 Hook）

目标：Service Check 的执行环境 与真实 Hive 运行环境 一致，避免 smoke 脚本"绕过"了我们在 hive-env 中的注入逻辑。

修改文件路径：

bash 复制代码 
/var/lib/ambari-server/resources/stacks/BIGTOP/3.2.0/services/HIVE/package/scripts

将 hcat_service_check.py（或对应脚本）替换为下述增强版本关键片段（已适配 enable_atlas_hook 条件与 Ambari 参数）：

python 复制代码 
# --- Atlas Hook 环境注入 ---
if params.enable_atlas_hook:
    atlas_hook_env_cmd = format(r'''
ATLAS_HOOK_DIR="{atlas_home}/hook/hive"

ATLAS_HOOK_JARS=$(
  {{
    ls "${{ATLAS_HOOK_DIR}}"/*.jar 2>/dev/null
    ls "${{ATLAS_HOOK_DIR}}/atlas-hive-plugin-impl"/*.jar 2>/dev/null
  }} | grep -v 'logback-classic' | tr '\n' ':' | sed 's/:$//'
)

if [ -n "${{ATLAS_HOOK_JARS}}" ]; then
  if [ -n "${{HIVE_AUX_JARS_PATH:-}}" ]; then
    export HIVE_AUX_JARS_PATH="${{HIVE_AUX_JARS_PATH}}:${{ATLAS_HOOK_JARS}}"
  else
    export HIVE_AUX_JARS_PATH="${{ATLAS_HOOK_JARS}}"
  fi
  export HIVE_AUX_JARS_PATH="$(echo "${{HIVE_AUX_JARS_PATH}}" | sed 's/^://;s/:$//;s/::\+/:/g')"
fi
''')
else:
    atlas_hook_env_cmd = ''

在 prepare/cleanup 两个动作前拼接 atlas_hook_env_cmd，确保 smoke 流程也加载 Hook：

python 复制代码 
prepare_cmd = format(
  "{kinit_cmd}{atlas_hook_env_cmd}\n"
  "env JAVA_HOME={java64_home} {tmp_dir}/hcatSmoke.sh hcatsmoke{unique} prepare {purge_tables}"
)
...
cleanup_cmd = format(
  "{kinit_cmd}{atlas_hook_env_cmd}\n"
  " {tmp_dir}/hcatSmoke.sh hcatsmoke{unique} cleanup {purge_tables}"
)

替换完成后 重启 ambari-server 使之生效。

六、验证闭环（kinit → smoke → Hook 解析）

bash 复制代码 
kinit -kt /etc/security/keytabs/smokeuser.headless.keytab ambari-qa-aaa@TTBIGDATA.COM
klist
bash 复制代码 
env JAVA_HOME=/opt/modules/jdk1.8.0_202 \
/var/lib/ambari-agent/tmp/hcatSmoke.sh hcatsmokeid000ac563_date360925 prepare true
sql 复制代码 
-- Beeline 连接后执行
show tables;
-- 不再出现 HiveHook ClassNotFound，且 post hooks 正常初始化

执行日志应出现我们注入的 Atlas Hook 相关 echo/环境变量，且不再报：
java.lang.ClassNotFoundException: org.apache.atlas.hive.hook.HiveHook。
