Streamsets Solr目标模块错误不让我直接从管道向Solr集合添加数据

Question

我已经构建并部署了以下docker-compose.yml文件：

services:
  solr1:
    container_name: solr1
    image: solr:5-slim
    ports:
      - "9981:9983"
      - "8981:8983"
    volumes:
      - data:/var/solr
      - ./solr_configs/schema.xml:/opt/solr/server/solr/configsets/mri_config/schema.xml
      - ./solr_configs/schema.xml:/opt/solr/server/solr/configsets/mri_config/conf/managed-schema
      - ./solr_configs:/opt/solr/server/solr/configsets/mri_config/conf
    environment:
      - ZK_HOST=zoo1:2181,zoo2:2181,zoo3:2181
    networks:
      - solr
    depends_on:
      - zoo1
      - zoo2
      - zoo3

  solr2:
    image: solr:5-slim
    container_name: solr2
    ports:
      - "9982:9983"
      - "8982:8983"
    volumes:
      - data:/var/solr
      - ./solr_configs/schema.xml:/opt/solr/server/solr/configsets/mri_config/schema.xml
      - ./solr_configs/schema.xml:/opt/solr/server/solr/configsets/mri_config/conf/managed-schema
      - ./solr_configs:/opt/solr/server/solr/configsets/mri_config/conf
    environment:
      - ZK_HOST=zoo1:2181,zoo2:2181,zoo3:2181
    networks:
      - solr
    depends_on:
      - zoo1
      - zoo2
      - zoo3

  solr3:
    image: solr:5-slim
    container_name: solr3
    ports:
      - "9983:9983"
      - "8983:8983"
    volumes:
      - data:/var/solr
      - ./solr_configs/schema.xml:/opt/solr/server/solr/configsets/mri_config/schema.xml
      - ./solr_configs/schema.xml:/opt/solr/server/solr/configsets/mri_config/conf/managed-schema
      - ./solr_configs:/opt/solr/server/solr/configsets/mri_config/conf
    environment:
      - ZK_HOST=zoo1:2181,zoo2:2181,zoo3:2181
    ports:
      - 9983:9983
      - 8983:8983
    networks:
      - solr
    depends_on:
      - zoo1
      - zoo2
      - zoo3

  zoo1:
    image: zookeeper:3.4
    container_name: zoo1
    restart: always
    hostname: zoo1
    ports:
      - 2181:2181
    environment:
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
    networks:
      - solr

  zoo2:
    image: zookeeper:3.4
    container_name: zoo2
    restart: always
    hostname: zoo2
    ports:
      - 2182:2181
    environment:
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
    networks:
      - solr

  zoo3:
    image: zookeeper:3.4
    container_name: zoo3
    restart: always
    hostname: zoo3
    ports:
      - 2183:2181
    environment:
      ZOO_MY_ID: 3
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
    networks:
      - solr

  sdc:
    image: streamsets/datacollector
    ports:
      - 18630:18630
    volumes:
      - /local/directory/path/streamsets:/data:rw
    networks:
      - solr

networks:
  solr:

volumes:
  data:

然后我通过执行创建了一个名为collection1

的Solr集合。

docker exec solr1 solr create -c collection1

在Streamsets中转换数据后，我通过从软件包管理器中添加Solr-6.1.0目标模块并随后重新启动sdc docker容器来安装并添加了Solr-6.1.0目标模块。这是我在流集中的SolrCloud设置和单节点设置的设置：

每次运行预览或管道时，都会出现错误，指出：

SOLR_3-无法连接到Solr实例：java.lang.ClassCastException：org.apache.solr.common.util.SimpleOrderedMap无法转换为java.util.Map

此错误是什么意思？我应该更改什么或添加到我的管道中，以便能够连接管道并将数据直接管道传输到Solr集合中？

这里也是该集合的Solr Admin UI state.json的附件图像。

非常感谢您的帮助。

我最终从程序包管理器安装了CDH 5.15.0程序包。这使我们能够连接到Docker容器中的Solr 5.5-slim。然后，在Solr目标模块的常规选项卡中，我们在登台库字段中选择CDH 5.15.0软件包，然后定义单节点信息以允许我们连接到Solr数据库。
