缺少Hive执行罐：/usr/local/hadoop/hive/lib/hive-exec-*.jar [英] Missing Hive Execution Jar: /usr/local/hadoop/hive/lib/hive-exec-*.jar

问题描述

我的Hadoop 1.0.4运行在我的Ubuntu机器上设置的单个节点集群上。

我做了以下步骤来下载并安装配置单元

 > svn co http://svn.apache.org/repos/asf/hive/trunk hive 
> cd hive 
  

我的hadoop安装文件夹是$ HADOOP_HOME / hive和$ HADOOP_HOME = / usr / local / hadoop 。我将.bashrc中的环境变量设置为/ home / hduser，这是我的Hadoop用户和$ JAVA_HOME。

  export HADOOP_HOME = / usr / local / hadoop 
 
 export HIVE_HOME = $ HADOOP_HOME / hive 
 
 export JAVA_HOME = / usr / lib / jvm / java-6-openjdk 
 $ / pre 
 
 
我还在我的$ PATH变量中添加了hadoop和hive的bin文件夹，如下所示：
  export PATH = $ PATH：$ HADOOP_HOME / bin 
 export PATH = $ HIVE_HOME / bin：$ PATH 
  
但是，当从CLI运行hive时，我收到以下错误。
  hduser @ somnath-laptop：/ usr / local / hadoop / hive $ bin / hive 
缺少Hive Execution Jar：/ usr / local / hadoop / hive / lib / hive- exec  -  *。jar 
  
我应该下载这个jar并将其添加到/ lib /还是在一些我需要配置的特定于hive的环境变量。任何建议都是非常有用的。
解决方案
我自己解决了问题，但不知道究竟发生了什么。 
 $ b 
按照我原来的问题提到的过程，我创建了$ HADOOP_HOME / hive，但是它给了我一个丢失的jar错误。
 
 
 
所以，我做的是：我下载了hive-0.10.0.tar.gz，并在$ HADOOP_HOME下解压缩。所以新创建的文件夹是$ HADOOP_HOME / hive-0.10.0。 
 
 
 
我将$ HADOOP_HOME / hive-0.10.0 / lib下的许多jar复制到$ HADOOP_HOME / hive / lib中，当我执行下一步时，
 
 
 
 $ HADOOP_HOME / hive> bin / hive 
 
 
 
它工作！请注意我的$ HIVE_HOME = $ HADOOP_HOME / hive和$ HIVE_HOME / bin添加到路径。 
希望这有助于有人面临类似的问题。
 
I have Hadoop 1.0.4 running on a single node cluster set up on my Ubuntu machine. 

I did the following steps to download and install the hive release
> svn co http://svn.apache.org/repos/asf/hive/trunk hive    
> cd hive
My hadoop install folder is $HADOOP_HOME/hive and $HADOOP_HOME=/usr/local/hadoop. I set both the environment variables in .bashrc under /home/hduser which is my Hadoop user and the $JAVA_HOME as well.
export HADOOP_HOME=/usr/local/hadoop

export HIVE_HOME=$HADOOP_HOME/hive

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk
I have also added the bin folder of both hadoop and hive in my $PATH variable as follows
export PATH=$PATH:$HADOOP_HOME/bin    
export PATH=$HIVE_HOME/bin:$PATH
But while running hive from CLI, I am getting the below error.
hduser@somnath-laptop:/usr/local/hadoop/hive$ bin/hive    
Missing Hive Execution Jar: /usr/local/hadoop/hive/lib/hive-exec-*.jar
Should I download this jar and add it to the /lib/ or is there some hive-specific environment variables that I need to configure. Any suggestion would be very helpful.
解决方案
I resolved the problem myself but not sure what exactly happened.

By following the process I mentioned in my original question, I created the $HADOOP_HOME/hive but it was giving me a missing jar error.

So, what I did was: I downloaded hive-0.10.0.tar.gz and extracted it under $HADOOP_HOME. So the newly created folder was $HADOOP_HOME/hive-0.10.0. 

I copied the entire lot of jars under $HADOOP_HOME/hive-0.10.0/lib to $HADOOP_HOME/hive/lib and when I executed next,

$HADOOP_HOME/hive> bin/hive

It worked! Please note my $HIVE_HOME=$HADOOP_HOME/hive and $HIVE_HOME/bin is added to path.
Hope this helps somebody facing similar problem.
