Now I want to add another context field like departmentType. I am not sure how to configure the suggester for multiple context fields. This is the suggester that used with single context fields and this is working fine. <searchComponent name="suggest" class="solr.SuggestComponent"> <lst name="suggester"> <str name="name"

环境篇：Atlas2.0.0兼容CDH6.2.0部署 Atlas 是什么? Atlas是一组可扩展和可扩展的核心基础治理服务，使企业能够有效地满足Hadoop中的合规性要求，并允许与整个企业数据生态系统集成。 Apache Atlas为组织提供了开放的元数据管理和治理功能，以建立其数据资产的目录，对这些资产进行分类和治理，并为数据科学家，分析师和数据治理团队提供围绕这些数据资产的协作功能。 如果没有Atlas 大数据表依赖问题不好解决，元数据管理需要自行开发，如：hive血缘依赖图 对于表依赖问题，没有一个可以查询的工具，不方便错误定位，即业务sql开发 官网： http://atlas.apache.org 表与表之间的血缘依赖 字段与字段之间的血缘依赖 1 Atlas 架构原理 2 Atlas 安装及使用 安装需要组件，HDFS、Yarn、Zookeeper、Kafka、Hbase、Solr、Hive，Python2.7环境 需要Maven3.5.0以上，jdk_151以上，python2.7。 2.1 下载源码包2.0.0，IDEA打开 2.2 修改相关版本与CDH版本对应 <hadoop.version>3.0.0</hadoop.version> <hbase.version>2.1.0</hbase.version> <kafka.version>2.1.0<
