Question

我在ubuntu中安装了hadoop，运行正常。

ubuntu:/home/hduser/hive-0.10.0-cdh4.3.1$ jps
2702 DataNode
3101 ResourceManager
4879 Jps
2948 SecondaryNameNode
3306 NodeManager

hadoop_version = Hadoop 2.0.0-cdh4.3.0

然后我从apache tarball安装了hive（hiv version-hive-0.10.0），我尝试运行bin / hive。但我收到了以下错误：

无法确定Hadoop版本信息。 hadoop version已退回：

/home/hduser/hadoop/etc/hadoop /usr/lib/jvm/jdk1.6.0_45/ 
Hadoop 2.0.0-cdh4.3.0
Subversion file:///var/lib/jenkins/workspace/CDH4.3.0-Packaging-Hadoop/build/cdh4/hadoop/2.0.0-cdh4.3.0/source/hadoop-common-project/hadoop-common -r 48a9315b342ca16de92fcc5be95ae3650629155a

This command was run using /home/hduser/hadoop/share/hadoop/common/hadoop-common-2.0.0-cdh4.3.0.jar

我尝试通过我的脚本知识解决但不能。当我伸出努力时，我发现它在下面的线上失败了：

if [[ "$HADOOP_VERSION" =~ $hadoop_version_re ]]; then

我尝试echo HADOOP_VERSION它没有返回任何内容，HADOOP_VERSION被定义为

HADOOP_VERSION=$($HADOOP version | awk '{if (NR == 1) {print $2;}}');

和$HADOOP version让我

我现在被打了一个星期。请帮帮我。感谢。

Answer 1

您的问题已经描述了这个问题。当脚本执行$HADOOP version时，它会预期输出如下：

Hadoop 2.0.0-cdh4.3.0
Subversion file:///var/lib/jenkins/workspace/CDH4.3.0-Packaging-Hadoop/build/cdh4/hadoop/2.0.0-cdh4.3.0/source/hadoop-common-project/hadoop-common -r 48a9315b342ca16de92fcc5be95ae3650629155a
Compiled by jenkins on Mon May 27 19:06:57 PDT 2013

 This command was run using /home/hduser/hadoop/share/hadoop/common/hadoop-common-2.0.0-cdh4.3.0.jar`

相反，其他一些输出依旧（可能是因为您修改了Hadoop中的一些脚本。检查conf / hadoop-env.sh）：

/home/hduser/hadoop/etc/hadoop
/usr/lib/jvm/jdk1.6.0_45/
Hadoop 2.0.0-cdh4.3.0
Subversion file:///var/lib/jenkins/workspace/CDH4.3.0-Packaging-Hadoop/build/cdh4/hadoop/2.0.0-cdh4.3.0/source/hadoop-common-project/hadoop-common -r 48a9315b342ca16de92fcc5be95ae3650629155a

 This command was run using /home/hduser/hadoop/share/hadoop/common/hadoop-common-2.0.0-cdh4.3.0.jar`

现在awk行不再找到所需的数字（在第2位）。

因此，解决方案是找出额外输出的来源并将其删除。

Answer 2

我有同样的问题，我通过在.profile中包含以下内容并再次采购来修复它。

导出HADOOP_VERSION =＆＃34; 2.0.0-cdh4.2.0＆＃34;

Answer 3

在Windows上，您可能遇到同样的问题。

实际上，如果将$HADOOP_HOME设置为dos路径（例如：C:\hadoop），则需要在cygwin中更改它。一种方法是将以下行放在.bashrc中：

export HADOOP_HOME="$(cygpath $HADOOP_HOME)"

Answer 4

执行以下命令：hadoop version

hduser@ubuntu:/usr/local/hadoop/sbin$ hadoop version

Answer 5

检查你的JAR PATH（JRE_HOME）

Answer 6

如果您在.bashrc文件中设置了export HADOOP_VERSION=2.0.0-cdh4.3.0或您的版本号，请对其进行评论或将＃放在前面，如#export HADOOP_VERSION=2.0.0-cdh4.3.0，然后运行配置单元，您将能够解决问题。

无法确定Hadoop版本信息
