我的电脑环境如下
软件名称版本Hadoop3.3.0hive3.1.3jdk1.8Elasticsearch7.10.2kibana7.10.2logstash7.10.2ES-Hadoop7.10.2
ES-Hadoop的引入
hadoop、hive和es的关系如下图中间有一个组件叫做ES-Hadoop是连接Hadoop和es的桥梁es的官网上提供了这个组件解决Hadoop和es之间的数据同步问题。 下面说一下数据同步的具体步骤
第一步去es的官网上下载ES-Hadoop组件
注意ES-Hadoop 的版本需要和es的版本是一致的 官网下载地址es的官网链接-点我 在输入框中输入es-hadoop在version版本处找到和你es相同的版本即可
第二步上传这个安装包到集群上解压完成后将其中的jar包上传到HDFS上你新建的目录
命令如下
hadoop fs -put elasticsearch-hadoop-7.10.2.jar /user/hive/warehouse/es_hadoop/第三步将这个jar包添加到hive中
在hive的终端下输入如下命令
add jar hdfs:///user/hive/warehouse/es_hadoop/elasticsearch-hadoop-7.10.2.jar;第四步在hive中创建临时表作为测试用
创建一个hive中的表并且添加上测试数据
CREATE EXTERNAL TABLE hive_test(name string, age int, hight int)
ROW FORMAT SERDE org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe
WITH SERDEPROPERTIES ( field.delim,, serialization.format,)
STORED AS INPUTFORMAT org.apache.hadoop.mapred.TextInputFormat
OUTPUTFORMAT org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat
LOCATIONhdfs://master:9000/user/hive/warehouse/pdata_dynamic.db/hive_test;
添加数据展示如下
hive select * from hive_test;
OK
吴占喜 30 175
令狐冲 50 180
任我行 60 160第五步创建hive到es的映射表
CREATE EXTERNAL TABLE es_hadoop_cluster(name string COMMENT from deserializer,age string COMMENT from deserializer,hight string COMMENT from deserializer)
ROW FORMAT SERDEorg.elasticsearch.hadoop.hive.EsSerDe
STORED BYorg.elasticsearch.hadoop.hive.EsStorageHandler
WITH SERDEPROPERTIES (serialization.format1)
LOCATIONhdfs://master:9000/user/hive/warehouse/pdata_dynamic.db/es_hadoop_cluster
TBLPROPERTIES (bucketing_version2,es.batch.write.retry.count6,es.batch.write.retry.wait60s,es.index.auto.createTRUE,es.index.number_of_replicas0,es.index.refresh_interval-1,es.mapping.namename:name,age:age,hight:hight,es.nodes172.16.27.133:9200,es.nodes.wan.onlyTRUE,es.resourcehive_to_es/_doc);映射表的参数说明
参数参数参数说明bucketing_version2es.batch.write.retry.count6es.batch.write.retry.wait60ses.index.auto.createTRUE通过Hadoop组件向Elasticsearch集群写入数据是否自动创建不存在的index true自动创建 false不会自动创建es.index.number_of_replicas0es.index.refresh_interval-1es.mapping.name7.10.2hive和es集群字段映射es.nodes指定Elasticsearch实例的访问地址建议使用内网地址。es.nodes.wan.onlyTRUE开启Elasticsearch集群在云上使用虚拟IP进行连接是否进行节点嗅探 true设置 false不设置es.resource7.10.2es集群中索引名称es.nodes.discoveryTRUE是否禁用节点发现true禁用 false不禁用es.input.use.sliced.partitionsTRUE是否使用slice分区 true使用。设置为true可能会导致索引在预读阶段的时间明显变长有时会远远超出查询数据所耗费的时间。建议设置为false以提高查询效率 false不使用。es.read.metadataFALSE操作Elasticsearch字段涉及到_id之类的内部字段请开启此属性。
第六步写同步SQL测试一下
同步SQL
insert into es_hadoop_cluster select * from hive_test;结果报错了nice正好演示一下这个错误怎么解决 报错信息中有一行Caused by: java.lang.ClassNotFoundException: org.elasticsearch.hadoop.hive.EsHiveInputFormat 报错原因在hive中执行add jar xxx 这个命令只在当前窗口下有效 解决方案1.每次执行insert into的时候执行下面的添加jar包的命令 add jar hdfs:///user/hive/warehouse/es_hadoop/elasticsearch-hadoop-7.10.2.jar; 2.将这个jar包作为永久的函数加载进来后面在补充再补充一下

Time taken: 16.482 seconds第七步查询一下映射表并去es集群上查询数据是否同步成功了
1.查询映射表
nice,又报错了报错如下 报错原因分析我之前做的时候将解压的所有包都放在hive的lib目录下了现在看来只需要一个即可将其余的都删除 解决方案删除多余的jar包在hive的lib的目录下
hive select * from es_hadoop_cluster;
OK

hive select * from es_hadoop_cluster ;

任我行 60 1602.在es集群上去进行查询
根据映射表中创建时的索引进行查询数据正常展示出来了nice 开心有问题欢迎留言交流
