hadoop编译过程当中遇到的错误

我用的环境（错误跟环境不要紧）：centos6.4,hadoop2.6.4（或者hadoop2.7.6或者hadoop2.6.5）

【错误1】：mvn clean install -DskipTests中遇到：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project hadoop-minikdc: Compilation failure: Compilation failure: 
[ERROR] error: error reading /root/.m2/repository/org/apache/directoryrver/apacheds-interceptor-kerberos/2.0.0-M15/apacheds-interceptor-kerberos-2.0.0-M15.jar; error in opening zip file
[ERROR] error: error reading /root/.m2/repository/org/apache/directoryrver/apacheds-interceptors-collective/2.0.0-M15/apacheds-interceptors-collective-2.0.0-M15.jar; error in opening zip file

截图：

错误缘由：下载的jar包有问题（可能不完整），因此报“error in opening zip file”

解决办法：从本机讲对应的jar包下载来，覆盖linux上maven库中有问题的jar包。

【错误2】：执行mvn package -Pdist,native -DskipTests -Dtar这一步的时候报报错：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (dist) on project hadoop-kms: An Ant BuildException has occured: exec returned: 2
[ERROR] around Ant part ...<exec dir="/home/hadoop/apps/hadoop2.6.4/hadoop-common-project/hadoop-kms/target" executable="sh" failonerror="true">... @ 10:120 in /home/hadoop/apps/hadoop2.6.4/hadoop-common-project/hadoop-kms/target/antrunbuild-main.xml
截图：

解决办法：

首先使用java -version查看版本号是否跟本身安装的版本号一致，若是不一致，那么执行命令ll /usr/bin/java检查指向，具体修改方法自行搜索；

若是java -version看到的版本号正常，那么进行下面的操做：

查看 hadoop-common-project/hadoop-kms/target/antrun/build-main.xml 文件中使用的apache-tomcat版本号，并下载（文件中有地址），而后放到目录 hadoop2.6.4/hadoop-common-project/hadoop-kms/downloads下

找downloads目录方法：

build-main.xml配置文件中有：

​​​​​​​<echo file="/home/hadoop/apps/hadoop2.6.4/hadoop-common-project/hadoop-kms/target/tomcat-untar.sh">cd &quot;/home/hadoop/apps/hadoop2.6.4/hadoop-common-project/hadoop-kms/target/tomcat.exp&quot;gzip -cd ../../downloads/apache-tomcat-6.0.41.tar.gz | tar xf -</echo>

其中的../../downloads/apache-tomcat-6.0.41.tar.gz就是该放的目录，../../是相对于tomcat-untar.sh来讲的，因此downloads目录应该是：/home/hadoop/apps/hadoop2.6.4/hadoop-common-project/hadoop-kms
