Pig和HCatalog

Question

当我运行"pig“时，我得到了以下错误。

Exception inthread"main"java.lang.NoClassDefFoundError:/usr/lib/hive/lib/libthrift-    
0/9/1/jar:/usr/lib/hive/lib/hive-exec-0/12/0/2/0/6/0-76/jar:/usr/lib/hive/lib/libfb303-

我已经按如下方式定义了所有环境变量(包括PIG_CLASSPATH)，还在pig.properties文件中定义了pig.additiona.jars

   export HADOOP_GROUP=hadoop ;
    export HADOOP_HOME=/usr/lib/hadoop
    export HCAT_HOME=/usr/lib/hcatalog
    export HIVE_HOME=/usr/lib/hive
    export templeton_host=$TEMPLETON_HOST
    export user_name=hcat
    export PIG_CLASSPATH=$HCAT_HOME/share/hcatalog/hcatalog-*.jar:\
    $HIVE_HOME/lib/hive-metastore-*.jar:$HIVE_HOME/lib/libthrift-*.jar:\
    $HIVE_HOME/lib/hive-exec-*.jar:$HIVE_HOME/lib/libfb303-*.jar:\
    $HIVE_HOME/lib/jdo2-api-*-ec.jar:$HIVE_HOME/conf:$HADOOP_CONF_DIR:\
    $HIVE_HOME/lib/slf4j-api-*.jar:/usr/lib/hive/lib/libthrift-    
    0.9.1.jar:/usr/lib/hive/lib/hive-exec-0.12.0.2.0.6.0-76.jar:/usr/lib/hive/lib/libfb303-
    0.9.0.jar:/usr/lib/hive/lib/jdo-api-3.0.1.jar:/usr/lib/hive/lib/slf4j-api-1.7.2.jar

    export PIG_OPTS=-Dhive.metastore.uris=thrift://$HIVE_HOST:$HIVE_PORT

在pig.properties文件中，

pig.additional.jars=/usr/lib/hive/lib/libthrift-0.9.1.jar:/usr/lib/hive/lib/hive-exec-   
   0.12.0.2.0.6.0-76.jar:/usr/lib/hive/lib/libfb303-0.9.0.jar:/usr/lib/hive/lib/jdo-api-  
   3.0.1.jar:/usr/lib/hive/lib/slf4j-api-1.7.2.jar

请让我知道如何解决这个问题。谢谢!

Answer 1

按照前面提到的步骤安装/配置HCatalog，并将其与here集成。

Answer 2

您需要在~./bashrc中配置环境变量

本地导出sqoop_HOME=/usr/ HCAT_HOME=/usr/local/hive/hcatalog /

• 导出sqoop
• 导出sqoop HIVE_HOME=/usr/local/hive
• 导出sqoop
