我是初学数据并尝试通过分布式缓存分发所有spring数据依赖项。但它没有用,没有找到有用的资源。
我在 application-context.xml 中的配置: -
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/hadoop"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:hdp="http://www.springframework.org/schema/hadoop"
xmlns:context="http://www.springframework.org/schema/context"

http://www.springframework.org/schema/hadoop http://www.springframework.org/schema/hadoop/spring-hadoop.xsd">
<hdp:configuration>
fs.defaultFS=${hdp.fs}
</hdp:configuration>
<hdp:job id="wordcountJob"
input-path="${wc.input.path}"
output-path="${wc.output.path}"
mapper="${wc.mapper}"
reducer="${wc.reducer}"/>
<hdp:cache create-symlink="true">
<hdp:classpath value="/user/hadoop/DistributedCache/spring-data-hadoop-2.3.0.RELEASE.jar" />
</hdp:cache>
<hdp:job-runner id="runner" job-ref="wordcountJob" run-at-startup="true"/>
<context:property-placeholder location="hadoop-configs.properties"/>
</beans:beans>
我试图将spring-data-hadoop jar分发给每个节点。但到目前为止,它还没有奏效。是这样的吗?任何帮助将不胜感激
答案 0 :(得分:0)
您可以在作业配置中添加它。
<hdp:job id="MaxTempJob"
input-path="${input.path}"
output-path="${output.path}"
jar-by-class="com.chanchal.MaxTemperature"
mapper="com.chanchal.MaxTemperatureMapper"
map-key="org.apache.hadoop.io.LongWritable"
map-value="org.apache.hadoop.io.Text"
libs="/lib/spring-data-hadoop-2.3.0.RELEASE.jar"
/>
lib
是项目的位置。
