我现在用的jdbc: https://github.com/jaykelin/clickhouse-jdbc/tree/0.1-SNAPSHOT 用的httpclient版本:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.2.5</version>
<scope>provided</scope>
</dependency>
@jaykelin 你好,我按你说的设置pom.xml,还是报同样的错误,麻烦看下我的pom.xml与你的有什么不同:

建议使用我提供的那个jdbc
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.2.5</version>
<scope>provided</scope>
</dependency>
这个jar的版本是没有 HttpClientConnectionManager 的
@jaykelin 我用的就是你说的那个jdbc,是不是还需要修改代码呢
`
<artifactId>clickhouse-jdbc</artifactId>
<version>0.1.40</version>
`
可以下载jdbc的代码,install到本地mvn仓库,完成jar依赖
Can you please help me? I am getting this error too, I tried a lot of pom.xml configurations. Can you please show valid pom.xml and commands for jar building?
@fibersel clone clickhouse-jdbc from https://github.com/jaykelin/clickhouse-jdbc/tree/0.1-SNAPSHOT cd ...../../clickhouse-jdbc && make install cd .../clickhouse-hdfs-loader && mvn clean package assembly:assembly -DskipTests
sorry, but i can't do make install, there is no any Makefile
my foult. it's mvn install
Here is full step-by-step guide for jar building:
git clone https://github.com/jaykelin/clickhouse-jdbc.git
git clone https://github.com/jaykelin/clickhouse-hdfs-loader.git
cd clickhouse-jdbs
git checkout 0.1-SNAPSHOT
mvn install -DskipTests
(tests run on clickhouse instance, running on your machine at port 8123, so we skip it)
cd ../clickhouse-hdfs-loader
mvn clean package assembly:assembly -DskipTests
after these commands you will get jars at "target" folder So you can submit hadoop job:
hadoop jar target/clickhouse-hdfs-loader-2.1.2-jar-with-dependencies.jar com.kugou.loader.clickhouse.ClickhouseHdfsLoader ...
@jaykelin , put these instruction to README please, it will make our life easier :)
@fibersel Thanks for the advice
当我执行任务时报错:

我看到有人说是httpclient版本问题, 我修改pom.xml中版本为4.5.5还是不行:
请问是什么原因呢?求解答下
