线程"main"中的异常java.lang.NoClassDefFoundError:org/apache/hadoop/hive/ql/CommandNeedRetryException [英] Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hive/ql/CommandNeedRetryException

问题描述

当我使用"hive shell"命令启动hive时.它给了我以下例外:

When I am starting hive using 'hive shell' command. Its giving me below exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hive/ql/CommandNeedRetryException 
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hive/common/LogUtils$LogInitializationException 
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hive.ql.CommandNeedRetryException 
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hive.common.LogUtils$LogInitializationException 

推荐答案

实际上，这是由于hadoop设置引起的.我已经明确设置了HADOOP_CLASSPATH(仅适用于Java jar)，并且在运行hive时，它需要更多的hadoop jar文件，并且同样是通过hive配置文件添加的.因此，我们需要在hadoop-env.sh中设置HADOOP_CLASSPATH，如下所示:

Actually this was due to hadoop setup. I have set the HADOOP_CLASSPATH explicitly (as Java jars only) and while running hive, it need some more hadoop jar files and the same is add through hive configuration file. So we need to set HADOOP_CLASSPATH in hadoop-env.sh as below

export HADOOP_CLASSPATH = $ {HADOOP_CLASSPATH}:{您以前的类路径}

export HADOOP_CLASSPATH = ${HADOOP_CLASSPATH}:{yours previous classpath}
