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。
./make-distribution.sh –hadoop 2.2.0 –with-yarn –tgz
./make-distribution.sh –hadoop 2.2.0 –with-yarn –with-hive –tgz
./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 1] [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 1]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。

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/0.4.0/mqtt-client-0.4.0.pom [warn] module not found: org.eclipse.paho#mqtt-client;0.4.0
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
