其中，hudi 的 docker-compose 是参考了 hudi 中的写法，但是在 hudi 中 hiveserver 和 adhoc 容器都需要挂载到本机的 hudi 目录，并且需要提前编译 hudi，这里将 hiveserver 和 adhoc 两个容器进行了重新编译，将需要的包和配置文件打在了镜像中，后续将不再依赖外部目录的挂载。

networks 需要使用自定义网络，预先需要创建好，因为 docker-compose 默认创建的网络名字是 {docker-compose.yml 文件所在的文件夹名}_{default}，“_” 在主机名中是不合法字符，后续访问中会出现类似错误：

ERROR 1105 (HY000): HMSClientException, msg: org.apache.hadoop.hive.metastore.api.MetaException: Got exception: java.net.URISyntaxException Illegal character in hostname at index 30: thrift://hivemetastore.compose_default:9083

可以预先使用命令创建 mynet：

docker network create mynet --driver bridge --subnet 172.18.0.0/16 --gateway 172.18.0.1

特例说明

MacOS 由于内部实现容器的方式不同，在部署时宿主机直接修改 max_map_count 值可能无法成功，需要先创建以下容器：

docker run -it --privileged --pid=host --name=change_count debian nsenter -t 1 -m -u -n -i sh

容器创建成功执行以下命令：

sysctl -w vm.max_map_count=2000000

然后 exit 退出，创建 Doris Docker 集群。

这里将 batch_1.json 数据进行了缩减，如需获取全量可以从这里下载：https://github.com/apache/hudi/blob/master/docker/demo/data/batch_1.json

执行 cat batch_1.json | kcat -b kafkabroker -t stock_ticks -P 就可以将数据导入 Kafka 中。

测试验证

使用 DeltaStreamer 导入数据

Hudi 提供了 DeltaStreamer 工具。该工具可以连接到各种数据源（包括Kafka）来拉取变更，并使用 upsert/insert 原语应用于 Hudi 表。这里使用该工具从 kafka 中下载 json 数据，并将其摄取到 COW 和 MOR 表中。如果文件系统中的表还不存在，此工具会自动初始化这些表。

docker exec -it adhoc-2 /bin/bash

# Run the following spark-submit command to execute the delta-streamer and ingest to stock_ticks_cow table in HDFS
spark-submit \
  --class org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer $HUDI_UTILITIES_BUNDLE \
  --table-type COPY_ON_WRITE \
  --source-class org.apache.hudi.utilities.sources.JsonKafkaSource \
  --source-ordering-field ts  \
  --target-base-path /user/hive/warehouse/stock_ticks_cow \
  --target-table stock_ticks_cow --props /var/demo/config/kafka-source.properties \
  --schemaprovider-class org.apache.hudi.utilities.schema.FilebasedSchemaProvider

# Run the following spark-submit command to execute the delta-streamer and ingest to stock_ticks_mor table in HDFS
spark-submit \
  --class org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer $HUDI_UTILITIES_BUNDLE \
  --table-type MERGE_ON_READ \
  --source-class org.apache.hudi.utilities.sources.JsonKafkaSource \

  --target-table stock_ticks_mor \
  --props /var/demo/config/kafka-source.properties \
  --schemaprovider-class org.apache.hudi.utilities.schema.FilebasedSchemaProvider \
  --disable-compaction

# As part of the setup (Look at setup_demo.sh), the configs needed for DeltaStreamer is uploaded to HDFS. The configs
# contain mostly Kafa connectivity settings, the avro-schema to be used for ingesting along with key and partitioning fields.

将 Hudi 中的数据同步到 Hive

将 HDFS 上的表同步到 Hive 中，包括创建 Hive 表、添加 partitions 等。

docker exec -it adhoc-2 /bin/bash

Doris 创建 Hudi catalog

CREATE CATALOG hudi PROPERTIES (
    'type'='hms',
    'hive.metastore.uris' = 'thrift://172.18.0.104:9083',
    'hive.version' = '2.3.3'
);

CREATE CATALOG hudi2 PROPERTIES (
    'type'='hms',
    'hive.metastore.uris' = 'thrift://hivemetastore:9083',
    'hive.version' = '2.3.3'
);

CREATE CATALOG hudi3 PROPERTIES (
    'type'='hms',
    'hive.metastore.uris' = 'thrift://172.18.0.104:9083',
    'hadoop.username' = 'hive',
    'dfs.nameservices'='namenode',
    'dfs.ha.namenodes.namenode'='nn1',
    'dfs.namenode.rpc-address.namenode.nn1'='172.18.0.100:8082',
    'dfs.client.failover.proxy.provider.your-nameservice'='org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider'
);

因为上面 hivemetastore 的 IP 为 172.18.0.104，所以这里这样指定。
