Centos 6.5 x64环境下 spark 1.6 maven 编译-- 已验证

Centos 6.5 x64

jdk 1.7

scala 2.10

maven 3.3.3

cd spark-1.6

export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"

mvn -Dhadoop.version=2.7.1 -Phadoop-2.6 -DskipTests clean package

关于部署包的生成：

编译源码后，加以配置就可以运行spark了，但是此时的目录过于庞大，有800M左右，部署起来不方便，所以需要生成部署包！

源码根目录下的make-distribution.sh可以生成部署包

注意 从spark1.1.0，开始支持maven的配置参数。该命令已经带有maven的编译过程，所以不需要先编译再打包!!

make-distribution.sh参数：

• –hadoop VERSION：打包时所用的Hadoop版本号，不加此参数时hadoop版本为1.0.4。
• –with-yarn：是否支持Hadoop YARN，不加参数时为不支持yarn。
• –with-hive：是否在Spark SQL 中支持hive，不加此参数时为不支持hive。
• –skip-java-test：是否在编译的过程中略过java测试，不加此参数时为略过。
• –with-tachyon：是否支持内存文件系统Tachyon，不加此参数时不支持tachyon。
• –tgz：在根目录下生成 spark-$VERSION-bin.tgz，不加此参数时不生成tgz文件，只生成/dist目录。
• –name NAME：和–tgz结合可以生成spark-$VERSION-bin-$NAME.tgz的部署包，不加此参数时NAME为hadoop的版本号。

     如果要生成spark支持yarn、hadoop2.2.0的部署包，只需要将源代码复制到指定目录，进入该目录后运行：

./make-distribution.sh –hadoop 2.2.0 –with-yarn –tgz

     如果要生成spark支持yarn、hive的部署包，只需要将源代码复制到指定目录，进入该目录后运行：

./make-distribution.sh –hadoop 2.2.0 –with-yarn –with-hive –tgz

     如果要生成spark支持yarn、hadoop2.2.0、techyon的部署包，只需要将源代码复制到指定目录，进入该目录后运行：

./make-distribution.sh –hadoop 2.2.0 –with-yarn –with-tachyon –tgz

生成在部署包位于根目录下，文件名类似于spark-1.0.0-bin-2.2.0.tgz。

可能出现的问题总结：

1.spark源码中的pom.xml中指定了maven的版本，所以要提交安装相对应的版本

2.内存不够

[ERROR] PermGen space -> [Help ]
[ERROR]
[ERROR] To see the full stack trace of the errors,re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR]
[ERROR] For more information about the errors and possible solutions,
please read the following articles:
[ERROR] [Help ]http://cwiki.apache.org/confluence/display/MAVEN/OutOfMemoryError

上面这个错误是因为编译的时候内存不够导致的，可以在编译的时候加大内存。

export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"

3.mqtt-client-0.4.0无法下载

[error] Server access Error: sun.security.validator.ValidatorException:
PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException:
unable to find valid certification path to requested target
url=https://repo.eclipse.org/content/repositories/paho-releases/
        org/eclipse/paho/mqtt-client/0.4./mqtt-client-0.4..pom
[warn]  module not found: org.eclipse.paho#mqtt-client;0.4.

这个错误是Maven无法下载mqtt-client-0.4.0.pom，因为他用到的是HTTPS协议。解决这个错误可以通过添加对repo.eclipse.org的信任从而解决这个问题。那如何解决呢？下载InstallCert.java类：

}

编译上面的类：

$ javac InstallCert.java

$ java InstallCert repo.eclipse.org

这样会在当前目录下面生成名为jssecacerts的文件，将这个文件拷贝到你java安装目录的$JAVA_HOME/lib/security/下面，然后上述问题即可解决。
