【原创】大叔经验分享（100）Atlas导入hive元数据

首先要有HIVE_HOME环境变量，

如果是apache，直接配置为解压目录；如果是CDH，设置如下：

# export HIVE_HOME=/opt/cloudera/parcels/CDH-5.16.1-1.cdh5.16.1.p0.3/lib/hive

执行导入

# bin/import-hive.sh
...

报错，查看日志

提示找不到atlas-application.properties，将其拷贝到hive conf目录

# cp conf/atlas-application.properties /etc/hive/conf/

再次执行

# bin/import-hive.sh

Failed to import Hive Meta Data!!!

还是报错，提示找不到类，从server目录下拷贝到hook/hive目录下

# cp server/webapp/atlas/WEB-INF/lib/jackson-jaxrs-1.8.3.jar hook/hive/atlas-hive-plugin-impl/
# cp server/webapp/atlas/WEB-INF/lib/jackson-jaxrs-json-provider-2.9.2.jar hook/hive/atlas-hive-plugin-impl/
# cp server/webapp/atlas/WEB-INF/lib/jackson-module-jaxb-annotations-2.9.8.jar hook/hive/atlas-hive-plugin-impl/

再次执行成功，到atlas里可以看到hive相关数据

导入成功
