hadoop編譯過程當中遇到的錯誤

我用的環境（錯誤跟環境不要緊）：centos6.4,hadoop2.6.4（或者hadoop2.7.6或者hadoop2.6.5）

【錯誤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

截圖：

錯誤緣由：下載的jar包有問題（可能不完整），因此報「error in opening zip file」

解決辦法：從本機講對應的jar包下載來，覆蓋linux上maven庫中有問題的jar包。

【錯誤2】：執行mvn package -Pdist,native -DskipTests -Dtar這一步的時候報報錯：
[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
截圖：

解決辦法：

首先使用java -version查看版本號是否跟本身安裝的版本號一致，若是不一致，那麼執行命令ll /usr/bin/java檢查指向，具體修改方法自行搜索；

若是java -version看到的版本號正常，那麼進行下面的操做：

查看 hadoop-common-project/hadoop-kms/target/antrun/build-main.xml 文件中使用的apache-tomcat版本號，並下載（文件中有地址），而後放到目錄 hadoop2.6.4/hadoop-common-project/hadoop-kms/downloads下

找downloads目錄方法：

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就是該放的目錄，../../是相對於tomcat-untar.sh來講的，因此downloads目錄應該是：/home/hadoop/apps/hadoop2.6.4/hadoop-common-project/hadoop-kms
