hadoop执行hbase插入表操作,出错:Stack trace: ExitCodeException exitCode=1:(xjl456852原创)

在执行hbase和mapreduce融合时,将hdfs上的文本文件插入到hbase中,我没有使用"胖包"(胖包就是将项目依赖的jar包放入项目打包后的lib目录中),而是直接将hbase的lib加入到了hadoop的classpath中.

我是将HBase的jar包加到/opt/modules/hadoop/etc/hadoop/hadoop-env.sh中。配置好这个文件,分发到各个节点,改这个配置不用重启集群.

TEMP=`ls /opt/modules/hbase/lib/*.jar`
HBASE_JARS=`echo $TEMP | sed 's/ /:/g'`
HADOOP_CLASSPATH=$HBASE_JARS

可以通过命令查看hadoop的classpath现在包含哪些jar包:

[hadoop@master ~]$ hdfs classpath

　　

运行hadoop的mapreduce程序

hadoop jar xx.jar input '表名'

 

执行后出错:

网上查询到需要在/opt/modules/hadoop/etc/hadoop/yarn-site.xml中加入mapreduce运行时需要的类库,需要设置yarn.application.classpath:

所以我在yarn-site.xml中加入了如下配置,并加入了hbase的lib目录,配置好这个文件,分发到各个节点,这个配置需要重启集群

<property>
  <name>yarn.application.classpath</name>
      <value>
           /opt/modules/hadoop/etc/*,
           /opt/modules/hadoop/etc/hadoop/*,
           /opt/modules/hadoop/lib/*,
           /opt/modules/hadoop/share/hadoop/common/*,
           /opt/modules/hadoop/share/hadoop/common/lib/*,
           /opt/modules/hadoop/share/hadoop/mapreduce/*,
           /opt/modules/hadoop/share/hadoop/mapreduce/lib/*,
           /opt/modules/hadoop/share/hadoop/hdfs/*,
           /opt/modules/hadoop/share/hadoop/hdfs/lib/*,
           /opt/modules/hadoop/share/hadoop/yarn/*,
           /opt/modules/hadoop/share/hadoop/yarn/lib/*,
		/opt/modules/hbase/lib/*
      </value>
</property>
